12/12 I have an external hard drive (in a case with a fan). If I want to
maximize the lifetime of the drive, should I leave it on 24/7 or turn
it off at the end of the day (~50% duty cycle)? It's in a low
vibration enviornment.
\_ All right, fine fine. Here's something which came off google:
http://themeyers.org/HomeRoast/Topic7316.htm
\_ Thanks. It's a bit roundabout, but the concensus seems to be
that leaving it on is good except for the fan, which isn't
that necessary in this situation.
\_ umm, you're going to take computer advice from a mailing
list for coffee roasters?
\_ Turn it off.
Scenario: Your hard drive fails after 3 years. Are you going
to kick yourself for having left it on 24/7, or for turning
it off at the end of the day each day?
\_ That's not helpful. Do I kick myself for wearing out the motor
faster, or for inducing thermal stresses turning it on and off? |

12/9 Can someone recommend a way to read the contents of a FreeBSD
partition with UFS filesystems from a Windows box? It's a laptop
disk which won't boot properly by itself, FreeBSD doesn't like the
USB case I've put it in very much, and I don't have a Mac handy. -John
\_ You need an NT (I'm assumming you are running NT version of Windows)
filesystem driver for UFS. Once that is installed you should be able
to read it. You need to basically buy this from someone. If
it was an ext2 partition I have a driver for it, but alas UFS
isn't amongst the list of highly utilized fs --williamc

1/23 Any recommendations for a Linux tool to merge two disk partitions into
one. Does the partition that will get deleted would need to me
empty? I don't want to loose the data that's on it. Thanks.
\_ Get PartitionMagic ($70 or steal), I believe it works on merging
Linux partitions. Get a PC running Windows, install it, then attach
the HD to a free IDE (or SCSI) port and repartition. Non-optimal
solution, but hey, you don't partition on a daily basis.
\_ PM has a boot disk version. You don't need to move the HD.
\_ partition-mergeTwoToOne is a good tool.
\_ You probably don't want to "lose" the data, either.
\_ hey you're so funny!

11/7 I have an XP installation that reboots itself before it finishes
booting up, and I'd like to do a fresh install but it was cd-key'd
by my old school and I don't know the key. Is there a way to get
the CD-key from the repair console or from a rescue disk?
\_ that is why I hate XP. This may sounds unproductive, but I would
just reinstall Windows 2000 instead. Same kernel, same File System

\_ Yea, some military doctors says her some of her

She herself remembers nothing except that she was

and product activation "features."
\_ Yes, there is. Look for "XPKey". It took me about 10 minutes to
find both a working key extractor and a new key generator. The
key generator took about 2 hours to create a valid key on my
ancient PIII. The key extractor takes zero time to find and display
your current key. No, I won't give you my name or put copies in
/tmp or anything like that. google.
\_ is this why MS wants to buy google?
\_ How about an URL from google?
\_ I'll sell you a full install CD (from Dell) for $60 obo, including
the certificate of authenticity.
\_ A little effort and you can find a copy of XP Corporate (same as
Professional, except without activation). That + XPKey will get you
working without activation. If you have a legal license of XP Pro,
it is (IMO) an ethical solution.
\_ Saving files off USENET isn't any effort. |

10/27 If I'm getting a new EIDE hard disk for my 4 year old computer, do I
have to worry about hardware incompatibilities? My old computer
has an EIDE drive in it, but I'm not sure what the deal is with
terms like Ultra ATA/133 and so on. Thanks.
\_ No. It'll work as expected. You may not get the super peak
performace the drive is capable of but you won't notice since
the rest of your computer is just as slow. I stuck a modern 120gb
drive into a first generation HP celeron box yesterday. The shitty
bios didn't know what to make of it but it worked when I put my
own c/h/s numbers in.
\_ uh, there might also be an addressing problem. the old computer
may only be able to address ~137 GB of a disk.

10/24 I bought an external USB case for a hard drive, and it came with a
fan attached to the power supply which constantly runs. If I just
have my hard drive in there can't I safely turn the (annoyingly loud)
fan off? thanks
\_ Just get a 2.5" enclosure and spend a bit more for a laptop drive.
Not only is it more transportable, you won't have to worry about a
fan.
\_ Drives can run hot which means you're shortening the life span of
the device. The same is true for all computer stuff. You can run
a 3.2 ghz P4 without a fan, too. It just won't run for more than
a few seconds before it shuts itself off or burns out.
\_ I thought P3s shut themselves down, but P4s and later throttle
its speed down until temperatures falls?
\_ If it was runing 100mhz would you consider that running?
\_ If it's a low-speed drive (5400rpm), then you might safely get
away with it. Anything higher, and what the above poster said is
true. Inside a regular computer case, all your parts depend on the
cooling the multiple fans provide.
\_ Detach fan. Close case. Do continuous read/writes on your hard
disk (defrag? large file copy?). Open case. If drive is too hot
to touch, put fan back on. While it's true that a 3.2 GHz P4 will
stop in a few seconds w/o fan, heat dissipation has varied widely
for 5400, 7200, and 10K drives of different makes and models.
\_ Risky. It's going to take some time for it to really heat up.
It'd be shame if it OP tested cold and then it died over night. |

10/22 My sister's computer has been making weird "clicky" sounds at startup,
and she's also having probs starting applications (win98). She's on
a dialup modem and uses those free AOL discs. The weirdest thing is
that when she checks her email (hotmail) the username "ihatedeva"
keeps popping up in the username field of the form. This is not her
email nor any of her roommates or anyone she knows. Has anyone else
seen/heard about this? Google shows one livejournal user called
ihatedeva, but nothing about viruses.
\_ clicky sounds: Your hard drive is due for imminent failure. Get
a new one. Reformat, re-install WinXP or Win2K.
ihatedeva: Someone clicked "Yes" in Internet Explorer when asked
whether they want to install a random ActiveX control. You have
adware! Install SpyBot and Norton AntiVirus.
\_ is ihatedeva specific to a certain adware program?
\_ I don't know; it's purely a guess that it's related to
adware. Also, there are settings in IE for auto-complete
and cookies that you can clean.
\_ ihatedeva = Roomate's friend who used your computer?
\_ ihatedeva = her password she accidentally typed into the wrong
field, now IE remembers it.
\_ Lesson: IE and yahoo and aol suck. I agree with the above, the HD
is going soon. Unless... is there a floppy in there? A bad cd? |

10/15 I am looking for an mp3 player for my brother as a gift. What
features should I look for in a low-end (<$100) player? I haven't
yet decided whether to get the small memory type or the larger
ones that fits a CD yet. Any brands I should get/avoid? TIA.
- brendal
\_ I got a Panasonic mp3/cd player for $50 that I like. Having the
CD capacity was a major factor in my choice though.
\_ does he run? if so, you have to get one of those non-CD ones.
does he like a large capacity (for < $100). Then get the
CD one.
\_ definitely a thing to consider. Even HD based players are
known to skip when running. As for quality, iRiver has a
die-hard following. And iRiver constantly releases firmware
updates to add features. Ogg supporting FW should be out
sometime this month for most of their products. I personally
have the iFP-380T from iRiver. Oh, and I heard Costco sells
a cheap flash player that acts as a usb storage device, with
the USB connector right on the device. But it doesn't have
any sort of display.
\_ I had the Creative Nomad. The one that doubles as a USB storage
device. It broke on me after the warranty period. I replaced it
with a Sonic Blue Rio and it's been fine ever since.
\_ Pony up the dough and get your brother the CW300. Search for this
on http://newegg.com. My brother got one and he loves it. See amazon
for the 5-star rating/reviews. Blows everything else out of the
water. I have a Creative Muvo, piece of crap compared to the CW300. |

10/10 My laptop hd is having problems. Won't boot. Plugged into USB hd
caddy, and see the two partitions on it from my desktop. (Both
running XP). Both partitions show up as drives from an explorer
window on the desktop, but accessing the second partition gives
errors like "incorrect parameter" or "drive not formatted." Tried
using Partition Magic 8 to copy the whole laptop hd to my desktop
hd, but it returned "Error #56, Can't read sector" or something to
that effect. Suspecting physical error, but software still seems
to detect the partitions. Can't afford to go to data recovery
specialist. What tools are there (Windows or Linux) that can help
me recover data off laptop drive?
\_ linux: dd each partition to a file on another drive
then try mounting file as a loopback device.
with like: mount -o loop -t type filename /mnt/tmp
"type" depends on the filsystem type. win98 is vfat. donno XP.

10/10 Well I need to build a new firewall seeing as my old Linux box is dead.
After figuring out my set up for my studio I've come to the conclusion
that I will have half a rack slot free while the other half is being
taken by a MIDI module. Well can't have that last slot empty now can
we? So I go over to http://www.mini-itx.com and see quite a few good things
there. Get plenty of ideas for my next home stereo and what not. Only
problem, I can't find a case that will be 2" high by 9.5" wide (half a
u). Anybody know where I can get one?
I'm not going to be slapping a ton of gear into this machine. The
board I'm thinking of getting is the EPIA CL10000 board. It has two
nics already there. The only thing I need to put in there would be
a compact flash to ide converter for the file system. Any other disk
space needed can be mounted off a central file server with samba if I
want. For logging I'll just use syslog-ng and log remotely.
So, anybody know where I can find a case to meet my requirements?

it, and don't bother using the drive for anything but swap. -John

9/23 I have some data tapes that I haven't touched in 5 years. I used
nbackup in DOS on a 486 to make the tapes. Using the same program
on the same computer, I am trying to restore those files. I was
able to open the tapes, but when I try to restore, it says
"Cannot access tape drive" or just keeps asking me to insert the
tape when it's already inserted. Is it possible that the tape is
old and that the data is lost, or is the problem more likely the
tape drive? How can I retrieve this data?
\_ Does it say this for *every* tape? Unless *all* your tapes have
been damaged by some environmental event or they were shitty tapes
to start with, it is more likely the tape drive is shot. If you
have a unix box with the right tape drive you should be able to
at least use dd to read raw data from the tapes as a test.
\_ Actually, since I posted that, I was able to get some data
from one of the tapes. But then it kept giving me error
messages again. I looked closely at the tape, and the tape
is physically only connected to one spool (this was not the
case originally), and it's not as easy as you might think
to get it back on the other spool neatly.
\_ I had this same thing happen years ago. There is an
"end of tape" optical sensor in the drive, and if it
gets dusty, the drive unspools the tapes. You could
try to put the tape back together after cleaning the
dust out of the drive, but I suspect you might be out
of luck. This is why I abandoned tapes, and switched
to hard disks backups. and disks don't make that
annoying whining sound when searching for files. Look
in the Sunday paper and get a 150GB disk for $90. use
an old extra computer as a backup server, or get an
external drive, but either way, make sure to spin it
up often: hard disks can die from stiction if left
unused in an "off" state for too long (years). |

\_ How about 'Memory manufacturers sue consumers over mem size'?
Said one spokesman "We're selling them 512MB chips, but they're
getting 536MB. We feel we should be compensated for that 24MB."
\_ this is good news, it is time to put them in the right place.
If the law suit succeeds, the next one should be SD/CF cards
Since they are also falsely advertised. I bought a 256MB SD
card, and it turns out it only holds 241MB that is about 15MB
of space missing. 15MB extra on a SD can store so much more info.

These days, half of any given order arrives damaged (scuffs/black marks on the book, bent covers, mashed corners, etc.) If I'd wanted my books pre-damaged, I'd have gone shopping at Barnes & Noble! \_ I've orders books and other stuff from them recently, never a problem. They will accept returns and satisfy the customer. \_ I had an excellent experience regarding this. My book cover was bent, and they replaced it and paid for the shipping. \_ yeah, amazon is much better customer service wise than say, http://half.com (where the 'half' stands for half-witted customer service, half-witted buyers, and half-witted sellers; on the other hand, ebayers seem much more responsible on the whole.) \_ oh yeah, i forgot, amazon did ship me a 10,000 Maniacs CD with a damaged case(CD was fine), but they included a new CD-case and a note saying "we noticed damage and have included a new case". The "damage" was a scratch on the CD-case. \_ I've seen a version of their shrink-wrap packaging that bends up the corners of soft-covered books. A supid design.

8/25 Do people actually verify md5 sums? I recently ftped a linux
distribution iso and installed it. It seems to run fine. Then
by chance I run md5sum on the image and the first disk failed.
Is this just some transmission error or something more sinister?
\_ freebsd ports do this automatically. You should probably try
pulling the image again and rechecking. it could be truly sinister,
it could just make your system unstable down the line. look at it
as a strong litmus test.
\_ I already did and the new download passed the check. I am
going to reinstall the whole thing. But if it is the installer
itself that got corrupted maliciously, should I worry about
all the partitions of my disks and all the disks that was
mounted when I did the installation? That would be really
too much pain.
\- based on the strength [sic] of the tcp checksum
and the error base rate you can figure out how often
you can expect an undetected tranmission error.
we made some calculations a few years ago and when you
started shoveling gigabytes around you needed to start
worrying about these and doing some kind of stronger
application level checksumming. lately i havent done any
measurements to see if the base error rate has gone down
[or up say in wireless or whatever] and what the new
expectations might me. however i certainly am not sur-
prised to hear large iso or tarballs coming over long
paths arrived frayed at the edges. if you are interested
in techical details and have a general familarity with
tcp, you can mail me. any discussion of this on say
NANOG? --psb
\_ Google, as a result of their work, keeps track of
these numbers. Look up their research.
\- oh yeah i remember asking the google folks
if they do higher level checks, what chksums
they ue etc as the copy around parts of the
they use etc as the copy around parts of the
cache. do they "publish" these things anywhere?

8/11 What's the fastest way to confirm that two 8GB files are exact

\_ on a reasonably fast PC, md5sum saturates the disk channel
while hardly using any CPU. so nothing is going to be
faster (less I/O).
\_ running an md5sum on the image, I get "File too large".
any other program you can recommend?
\_ md5sum compiled with large file support

8/11 How does one determine which debian CD a specific package is on.
I've searced google and debian, and can't find out where to look.
\_ No reason to. You use CD1 to install, and then net to grab the
rest. If you don't have net, put the package on a CD or on a
floppy, and use dpkg to install.
\_ Well, actually I DO have a reason: I've installed debian
(via my net) for somebody who doesn't have good net, and I
want him to have the option to easily install more packages
from CD in the future, as needed. I would like to know which
CD's contain which packages, so that I can possibly rule out
downloading all 7 CD's with jigdo.
\_ I guess you could install your own system packages with
apt-get install package --download so you save the debs
and then burn those to cd
\_ 'the .jigdo file for a CD contains a list of all packages that
are on the CD. The files are compressed with gzip, so use
"zcat somefile.jigdo | less" or similar to view them.' |

8/1 "When one watches some tired hack on the platform mechanically
repeating the familiar phrases--'bestial atrocities', 'iron heel',
'bloodstained tyranny', 'free peoples of the world', 'stand
shoulder to shoulder'--one often has a curious feeling that one is
not watching a live human being but some kind of dummy: a feeling
which suddenly becomes stronger at moments when a light catches
the speaker's spectacles and turns them into blank discs which seem
to have no eyes behind them."

buy another cd from those evil motherfuckers ever again as long

\_ Ditto. -John
\_ So all three of you are going to stop buying music and

\_ I barely ever watch TV, rarely listen to radio,
and have bought 1 CD set in 9 months, in addition
to very rarely burning a copy off a friend. So
why shouldn't I be able to change my consumption
habits because of something I loathe? -John
\_ If you don't buy music then a boycott doesn't
mean anything. I'm going to launch a boycott
of Russian wines.
\_ I've found an acceptable compromise is to buy only used
CD's. This allows me to consume new music, without
directly supporting the RIAA. Also, since there are great
independent music stores in the Bay Area, I can support
local business. I think it's a good balance. On a side
note, I think it would be cool if someone implemented tip
jars for used CD's. Basically, when you buy a used CD, you
can voluntarily pay a few bucks extra, and that money gets
passed directly to the artist. If artists saw significant
revenue from something like this, it might encourage them
to pursue alternatives to contracting away all rights to
the majors, and this, in turn, could lead to real choice in
the music market. -dans
\_ tip jars? you think raw cash on the counter top is going
to go to the artist and each will get the right amount?
\_ I always have sharing turned off. I'm a leecher. I'll worry about
the RIAA once they start cracking down on those people.

\_ why would you think that a spinning platter would be faster than
solid state? -tom
\_ because you had a lot of memory keys that worked at USB speed,
and it wasn't unreasonable to assume that the flash memory
itself was about as fast as the USB 1.1 interface speed. -!op
\_ aren't there slow elements in a microdrive? Like say MOVING PARTS?
\_ maybe spin up, disk seek time? Isn't flash pretty fast?
\_ What's your interface? USB 1.1, 2.0, or FireWire? Even if it's
one of the last two, you have to remember it wasn't too long ago
you had 4 GB full-size hard drives with < 5 MB/s transfer.
I can imagine flash memory can be 5 MB/s or faster. I just
looked it up, and an IBM microdrive has a 5.6 MB/s media transfer
rate.
\_ Perhaps within a camera? My Canon S45 takes both compact flash
& microdrives
\_ I did another search, and one page has a microdrive using
a CompactFlash II interface. The drive has a max sustained
transfer rate of 4.2 MB/s, whereas the interface can go
up to 13.3 MB/s. So sure, you can have flash memory faster
than the microdrive.
\_ Dunno why you'd want microdrive in a camera anyway.
Compact Flash costs less and has no moving parts
\_ because there was a time when microdrives
were much larger than compactflash
\- i use microdrives and 256, 512 CFs. is the
data xfer rate really a big deal? i rarely
am shooting continuous mode ... and suppose
it is epislon faster on playback but that sucks

would for sure prefer one over the other is if
you are going to altitude. then pick cf. --psb

6/23 What exactly is a refurbished hard drive? I've been running
my replacement Seagate refurb drive for a few weeks and
ActiveSMART already thinks its going to fail in a 2 weeks.
Do they just low-level format all the defective drives and
reship them out?
\_ Please tell me this is a troll.
\_ well, it's a chance you took, and be a man and live with it.
\_ well, if it is true, this is class action lawsuit material.
\_ So you scored in the bottom quartile on the LSATs huh?
\_ chance he took? many hard drive manufacturers replace returned
drives with refurbished ones. It's as if consumers generally
get to choose what kind of replacements they get. anyhow, it's
still under warranty, right?
\_ Yea. But remember you loose $$ for shipping the defective
\_ "lose"
drive back everytime and warranty time while doing the
swap. (It also wastes your valuable time and effort.)
So if I have to swap a drive a few times during its 3 year
warranty, the effective cost is incredibly higher than
the original purchase price. This is wrong.
The consumer shouldn't haveta pay for the manufacturer's
defects when a product is still under warranty.
\_ I personally had better luck with my IBM SCSI harddrive.
I mean, for some reason SCSI harddrive gets much better
treatment than the IDE counter part. Having said that,
if I have choice, i really don't want to go through that
again. A defective Harddrive is a pain in the butt.
\_ Yeah, and you pay for it. At least it use to be true
that each and every SCSI drive is tested, while IDE
drives are only batch tested.
\_ This is a case of getting what you paid for. Don't ever buy
refurb drives. Period. --Motd Storage Guru
\_ Hrm. I've had very good luck with all my refurb
drives. I haven't lost any. Then again, I'm talking
about 1995 SCSI drives that work even after they start
to lose their bearings. But yeah, I wouldn't touch a
refurb IDE drive.
\_ Do you use the refurbs as temp space or for real data? -MSG
\_ I don't use them any more, because of space limitations,
however, I used them for years as my only storage, without
backups. Drives *used* to be reliable, even if refurb.
\_ I second this. My failure rate on refurbed drives is probably
10X what it is on new ones.
\_ I never buy refurb drives. I buy retail drives that fail
in a few months and get refurb drives in exchange. Perhaps
the guru could enlighten us on the best storage strategy in
his/her opinion.
\_ Depends on how much cash you've got and how important your
data is. For home use, a simple IDE mirror is probably a
good choice. For work I do raid3,4,5, mirrors, or 3,4,5
plus mirror for some stuff. Which of 3,4,5 I use and whether
or not it gets mirrored as well depends on what data goes on
it. Nothing is refurb. Things like the database goes on
fiber channel with stripe and mirror. Customer owned data
is raid4 or raid5 on IDE. Only a little bit of scsi here and
there. I figure if I'm going to shell out scsi level prices
I might as well get fiber channel and be done with it. -MSG |

decent mb with an athlon 2400+ (or faster) along with about
512 MB DDR RAM and a couple of 80 or 100 GB ATA/100 drives.
It will cheaper and faster than a Dell and just about as
reliable (provided you run a decent OS on it).
\_ for under 500 there are lots of random vendors on the net willing
to custom build. choose good motherboard, choose a cpu based on
the heat it puts out, not it's speed, choose good fans and put it
in well vented place, put in slower, lower heat drives and mirror
them, put in N+1 power supplies. it's sad to see the rest of you

replace a lot of maxtor drives. I hardly ever replace scsi or FC
drives except Fujitsu which I don't allow in my machines anymore.
In general IDE drives are not reliable, period. Get what you pay
for in the data storage world. All drives will break at the least
convenient time. That's what raid is for.
\_ For those interested, IBM bought Fujitsu a short time ago. I
don't know if it's just Fujitsu's IDEs or if IBM's using all
Fujitsu all the time.
\_ actually you got that backwards. IBM sold it's storage
business / division to Fujitsu. Fujitsu now manufactures
and sells what were IBM drives (such as the Deskstar and

\_ John, you can use any of a number of scsi<->ide external raid array
units which handles raid in hardware and exposes a single 'drive'
to the unix system. Typical box has 8 slots and handles raid5.
You aren't specific enough about your needs and budget, but from
what you say I might slap a bunch of 80/100/120 gig drives in a
box and do raid5. If the data is important enough, I'd mirror it
too. Do not buy 3ware cards. --raid guy and 3ware victim
\_ Good tip, thanks. I just need something that's fault
tolerant if a single disk goes--don't need hot-swap, which
is why I was thinking vinum (this'll all get backed up
anyway. The prices below (~$500-600) are what I'm looking
for--got any specific tips on disk boxes? I can't find any
decent ones in stores over here, and don't really know what
to look for online. Thanks! -John
\_ You might get an old "K2" raid box off ebay or something
like that. External hw raid boxes might be out of your
price range if you've only got $600 for one, but a used
one might go for that. An alternative would be to get
a 4 or 6 disk 3u case with hot swap support for ide and
then just build your unix box from that. It'll be less
expensive and probably still get you what you want. I
think you can get a case *and* disks for under $1000.
\_ Why not just buy a pair of 250GB EIDE disks and mirror them?
$258 for a 250GB hard disk....
\_ The best price/storage ratio is currently around 120G, for $100
a piece. $300 for a 240G RAID 5 solution across 3 disks.
Add in $300 for a 3ware escalade 7500-4LP ATA RAID controller if
you don't want to do RAID in software.

\_ What would you suggest for similar price/functionality?
\_ see my comment above to John about K2 boxes and 3u
hot swap ide cases.
\_ 1 TB IDE-to-SCSI hardware RAID is < $5000 . Uses 6 200 GB
disks. I am sure there are smaller versions for less. --dim
\_ Where can I find one of these?
\_ I thought FreeBSD's SCSI support was much better than IDE.
If you're willing to pay for RAID you'd do as well to go
straight SCSI.
\_ because scsi drives cost several times more per meg and
most people don't need scsi? it just has to work.
\_ The interface *is* SCSI. The disks are not. It connects
to a SCSI card and uses a SCSI driver, hence IDE-> SCSI. I
got mine at Western Scientific. --dim
\_ I believe the person meant "scsi->scsi" when they said
"straight scsi". IE: not IDE drives.
\_ No shit, but he also said "FreeBSD's SCSI support".
It *does* use the freaking SCSI driver, genius!
\_ hey dim, back to reading comp 1A for you. you're
the only one here who didn't know what everyone was
talking about.
\_ I think that would be you. Take your own advice.
\_ Actually, I was questioning the 1TB IDE-to-SCSI
part. I guess he meant IDE disks, SCSI interface,
which I would call SCSI-to-IDE. Using IDE to
access SCSI disks is the worst of both worlds,
which I think everyone agrees on. |

\_ apparently it's an existing drive that has worked for awhile
\_ Try kicking it, that sometimes works. Do you really expect
to solve your hardware problem on the motd? Hire a
technician.
\_ Is it by Maxtor?
\_ One known problem is that sometimes fw hd's that are put to
sleep aren't sent the awake command. Only way to fix this is
to shutdown the computer, unplug the drive, replug the drive
and then reboot.
In some cases, there are problems with bus powered drives
because the computer can't provide sufficient power over the
cable or there are too many devices plugged into the bus.
If the hd is bus powered, try switching to a standalone ps.
Also is the drive detected on the fw bus? You can check this with
Apple System Profiler by clicking on the Devices and Volumes
tab. In MacOSX ASP is /Applications/Utilites/Apple System Profiler.
In OS9 it should be in <Boot Hd>/Utilites/Apple System Profiler
or <Boot Hd>/Applications (Mac OS 9)/Utilites/Apple System Profiler.
If the drive isn't detected, turn it off, wait a few seconds,
turn it on and type CMD-R in the ASP window. If the drive is
detected at this point and it still won't mount, you will need
to use Disk Utility (OS X) or Disk First Aid and/or Drive Setup
(OS 9) to see if there are any problems with the fs on the drive.
If there are problems that Disk Utility or Disk First Aid can't
fix, you probably will need to get a copy of something like
Disk Warrior from Alsoft to fix the problems. |

normal disk. anyone know the name of this project or user?
\_ The project you describe is the Distributed Internet Backup
System (DIBS) developed by Emin Martinian and available at
http://www.csua.berkeley.edu/~emin/source_code/dibs/index.html -emin
\_ thanks
\- how are you determining what to incrementally backup?
are you looking at file timestamps? is the unit of change
a file or a block of data? i.e. if 1 byte is appended
to a 100meg file, does a 100mb get xferred? does this use
rsync under the hood? ok tnx. --psb
\_ if you're interested in that sort of stuff, try
http://oceanstore.cs.berkeley.edu
\_ Emin, were you a part of Kubi's group?
\_ OceanStore is a great project but it has different
goals. DIBS is designed to provide a way for people
to exchange files for backups in a secure, robust
way without requiring a central authority. -emin
\_ DIBS stores an MD5 hash for each file and does a full
backup of any file which changes. Rsync is not used
because DIBS uses encryption and erasure correction
coding and that is difficult to combine with rsync.
Also, DIBS is peer-to-peer while rsync requires you
to have accounts on both ends. -emin
\- yeah i have some limited familiarity with oceanstor
but again for something lightweight i am curious
about this dibs thing. we hacked up something we
call the "storagelocker" with ssh keys and some
other access control technology and a big perl
script ... it works ok as a palce to write and
recover a bitstream but it would be nice to have
some smarts to reduce the traffic volume.
BTW, does anyone know if the hummingbird fs
was ever released and what performance stats
look like? --psb
\_ Although I'm tooting my own horn, I think DIBS
is what you are looking for. The way I use DIBS
is to put links to everything I want backed up in
a special directory and DIBS automatically and
incrementally makes backups to other machines. -emin
\- ok i will analyze it and let you know
if i incorporate it into a front end
to the StorageLocker(tm) ok tnx --psb
\_ Emin, were you a part of Kubi's group?
\_ No. I was in Zakhor's group at Berkeley and I'm in the
DSP group at MIT. I work on DIBS because I think it's
cool; the stuff I do for "research" is much different. -emin
\_ Haven't companies been storing backup tapes or disks at separate
physical locations for years? He's not the first to realize that
a flood or fire would destroy any local backups, is he? |

\_ dd
\_ I bought ghost (norton systemworks, actually) for cheaps

to waste an entire box on windows either.
\- how do image an HD w/ dd?
\_ Something like: dd if=/dev/hda of=/tmp/hda.img
You might need the conv=osync or conv=notrunc
option along with the bs=<block size> option
since the default block size on linux is 1024b
while I think athat POSIX dd stipulates 512b.
\_ at least crank you bs to something large or
else your dd will take FOREVER

\_ not for 2.5" HDDs. there are some 3.5" HDD enclosures that

\- i gave this some more thought. i dont know where you are
going [what kinds of conditions you will be facing] or
how long you will be gone or how many pix you expect to
take, but i think a not unreasonable idea is to beg/borrow/
steal as many compact flash/micro drives as you can from
your friends. keep in mind some drives may not work at
altitude, and i'd be a little nervous about carrying all
on one potentially fragile digital wallet ... especially
under harsh conditions ... altitude, dusty, crossing
streams etc. are you sure you will need 10gigs? i think
jpegs shot at 2-3megs are pretty decent quality and that is
300+ shots on a 1gb microdrive. if you were an associate of

ass, i would probably loan you my digital media in return
for lunch or even a good postcard. if we are talking about

if the Wallet fails, the hard disk inside will likely still
be usable. -tom

\_ or an XBox!
\_ well... I made the iPod remark in light of psb's

your photos on it for just $200 and you'd be socking
it to Microsoft. Modchips rule.
\_ how is buying products from Microsoft "socking it
to Microsoft"?
\_ supposedly Xboxes are sold at a loss.
\_ of course if you buy one microsoft gets to add
1 to the numbers of xboes sold column which
is a big deal. The fact that the xbox is
outselling the gamecube is killing the cube.

And, isn't the Certificate of Authenticity usually

\_ The stickers come off. I put them on the CDROM
package. It should be transferable, given tha
I've never booted. You should be able to call
MS and demand a transfer if you've got the
certificate of authenticity.
I've never booted nor agreed to any licensing

that if you have to reinstall Windows, it's

1/11 A power outage caused my LINUX computer to crash and fsck can't fix
the disk because of a bad superblock. I tried everything in
the fsck and e2fsck and nothing fixes the bad superblock. Any
suggestions for fixing things or partially recovering data?
\_ superblock is repeated every 5000 blocks or something like that.
you can use some tool (something like mkfs... ask MOTD for detail)
to get a list of it. Chances are, you will have a working
superblock. Then, you use fsck manually specify the superblock
you just found. I personally has gone though this many times, and
felt that Linux is a lot more fragile than I would like because
of this reason.
\_ Ok, not trying to start another FreeBSD vs Linux flame war but
somebody has to ask. Did Linux people wrote they own filesystem
or did they borrowed heavily from *BSD?
\_ sometimes, mke2fs creates backup superblocks? did it?
also, I think the ext3 file system is more durable (next time)
\_ fsck -b 32 (see man pages) Or use a journalled file system
\_ Sometimes you can mount bad filesystems read-only and extract
data. I was able to do this on a FreeBSD partition with hard
errors and extract a fair amount of data before the disk
stopped responding altogether. YMMV.
\_ Just wondering, were you using ext3 or any of other journaling
file systems at the moment?
\_ Oh dear, another person learns the hard way that linux isn't
production quality. Eventually you kids will figure it out and
move on to real OS's with real file systems or you'll stop putting
useful data on bad OS's, at least. No one ever think it'll happen
to them.... Ext2 is a POS. Ext3 is a POS+bad journaling. Do not
trust any valuable data on these filesystems. Valuable means
you wouldn't /bin/rm it yourself. My cheap ass employer puts many
many terabytes of very valuable data on ext2 with no backups. We
lose data all the time on those systems but not on the real ones.
\_ My brother-in-law started a new job, sort of night-watchman
for their computer systems. A power-outage caused
crashes (UPS wasn't regularly tested) Only later did they
find data had been corrupted. Something to do with the
type of cheap linux disk and cache flushing or something.
\_ is there a semi-formal discussion of this anywhere?
something you can point the money/management people in
company to?
\_ Please give some examples of better filesystems.
\_ These people sound like FreeBSD bigots. I bet they have
UFS in mind. Still, not even UFS will save you from a disk
crash.
\_ No, but ext2fs at least is by default mounted async b/c
of the slow metadata updates (rm -r/tar x taking forever)
Async + power outage = major fs problems. If you mount
sync, your performance goes to shit. Ext3 and FFS +
soft updates both solve this problem.
\_ No. I wrote the "Oh dear" comment. I don't have *any*
Freebsd systems. You sound like a linux zealot defending
your beloved POS at all costs with no sense. Ext3 is a
huge joke. When you take a POS ext2 system which will
lose data on an idle system and "bolt on" a crappy wannabe
\_ Please give examples of better filesystems
pseudo-journaling system like Ext3 you don't get a JFS,
you get a crappy ext2 FS with crappy bolted on journaling.
His disk was probably bad *before* the disk crash and he
didn't know because he hadn't power cycled in months. He
likely didn't have a disk crash from the power outage. He
probably had an ext2 barf all over his disk earlier and
it didn't show until he needed to get that super block.
\_ Ok, I'll bite. What makes ext3 a "pseudo journaling"
file system and why its journaling is considered as
"crappy bolted on journaling"?
\_ Please give examples of filesystems better than etx3
\_ reiser?
\_ vxfs. wafl. xfs (real xfs)
\_ if you're talking about Linux file systems, ext3
is the safest choice and it is "blessed" by the
leading kernel developers. I disagree with the rants
about ext2/ext3 here. We used ext2 at work. We had
power outages. Did we have to wait for hours for
fsck to complete? Yes. Did we lose any data? No.
Ok, maybe we were lucky. Now we're using ext3. We
had no problems with it whatsoever. We never had
to fsck a file system, never lost any data. And
by the way, vxfs is available on Linux too,
as a part of Veritas foundation suite, if you'd
like to use a "real" file system..
\_ Thanks, I like your practical viewpoint.
\_ If your data is important to you, you will use RAID. Disk failures
happen under any O/S and there is nothing you can do about it
but use redundancy. Anyone who tells you otherwise is full of crap.
\_ I wouldn't stop at RAID. You need to backup your RAID too.
A single RAID box could be taken out by a power surge. |

1/4 Is there a reason why a card reader (compact flash or smartmedia)
would be limited to 1.5Mbps? Is it a function of the media or
something to do with the USB connection? How does an iPod get
around this limit?
\_ maximum speed of USB 1.1 is 1.5 Mbps. Firewire card readers exist.
As for iPods: 1. they use Firewire, not USB. 2. they use HDDs, not
flash. What the heck are you talking about?
\_ Maximum speed of USB 1.1 is 12 Mbps >> 1.5 Mbps. I know
that iPods use firewire; I asked because the hardware I'm
talking about is a Microdrive (type II CF), which probably
isn't dissimilar to a normal harddrive. I'm basically
wondering if I can achieve a higher throughput with a
different cardreader (eg, with firewire), or if it will be
the same because of a limitation in the compact flash spec.
\_ iPod drives are generally faster than Microdrives but the
limiting factor is the limitation of USB. iPod's Firewire
connection runs at up to 400Mb/s while USB 1.1 only runs
at 12Mb/s (whole order of magnitude diff).
\_ I've seen some USB2.0 card readers, and the fastest
is 6MBps, which falls well short of the possible max
USB2.0 speed of 60MBps, so there's got to be an issue
with the card specification as well.
\_ sorry, I misread (and meant) MBps, not Mbps. Firewire CF
readers are faster, yes. |

\_ doesn't elite pirated software just mean a pirated copy of

I just want something that will work and isn't going to cost me an arm and a leg like EMC, Hitachi, or IBM and I sure as hell don't want to start building my own. Thanks! \_ I'd be wary of any ATA array. IDE just isn't designed for large file service projects. Also, this sort of thing looks like super overkill for what you describe. I suggest finding a good supplier of prebuilt *nix boxes, preferably something running a BSD tcp stack for the sake of NFS. I found a fibre channel array from http://corpsys.com that runs $1700 per .5TB. Had no trouble with it yet under windows 2k, mandrake, and freebsd. Alternatively, you may want to look at the Sun A1000 line. --scotsman \_ I would not consider the XServe as a general-purpose server at this point. Apple just doesn't have a server pedigree (except a pedigree of abandoning their server products). -tom \_ apple's xserve is an incredible piece of hardware, but overkill for what you need. build a box from http://pixelusa.com. also, dell has $1k 1U servers with one year of on site support and two more years of by-mail support. \_ Solaris has a great NFS support and the most featureful NFS implementation. Why would you want to serve Solaris client with anything other than a Solaris server? \_ because Sun's low-end server hardware sucks. \_ In what respect? Do you really need 3GHz Athlon CPU on an NFS server? Take a look at Sun Fire V120, a very decent low-end server. \_ their hardware also is unreasonably expensive, as is support as well as people who know solaris. \_ A configuration with 1 GB RAM, 72 GB of disk, and a 650-mhz processor is $6000. You can get 3 much faster Intel boxes for that much. \_ What they gain in speed, they loose in software robustness and support. Specially, if you need an NFSserver, the question should be a no brainer. Also, who pays the list price for Sun hardware? Talk to a salesman. They'll slash the price by up to 50% depending on how deep your pockets are. \_ Mylex DAC960 controller. You can put together a real good x86 server for <<< $5k. Equivalent performance (and yes reliability) from Sun is gonna cost you three times as much, at least. And don't tell me Sun equipment is more reliable; some of my clients run thousands of high-load servers, and the Compaqs and Dells and other PC boxes of their world don't suffer any more outages. -John \_ I don't want to 'put together' 20+ new boxes. \_ ah. nweaver. \_ what software robustness and support do they lose? only if you screw together some parts from Fry's. \_ You get incomplete and unstable NFS support and funky RAID software. See the original poster's requirements. In addition to the IDE flakiness that someone mentioned, AFAIK, you can't mirror the boot disk on the xserve since it does not have an internal RAID controller and OS X probably does not support putting / on a software RAID device. Would you really like to take your server down for hours when the boot disk fails? If you're looking for a cost effective SCSI array consider the new Sun D2 (JBOD) or the 3310 series (hardware RAID). \_ Read the link above: OS X supports RAID devices. \_ But it doesn't support putting your root file system on software RAID. \- does apples weird file system with its weird case issues manifest themselves over nfs? this is a real annoyance for me when Makefile = makefile, configure = Configure etc. ok tnx. --psb \_ Forget software RAID anyway.

\_ I put it near the beginning, but these days when main memory
is 1 gb or greater and much much faster than disk, it doesn't
really matter that your placement will make vm a bit faster,
since the overhead is just so damn high.
\_ so it makes absolutly no performance boost to put swap at

\_ if you're swapping, you've already lost. -tom
\_ Even on a budget system the disk runs at 7200 rpm and
has a 2 or 4 mb buffer. Whatever speedup you get by
"optimal" placement will be unnoticable with such a
disk. The thing to worry about these days is getting
the fastest ddr ram you can find and making sure that
it is interleaved properly.

that you're more likely on average to swing the head less.
`\_ Even the slowest RAM is 8 orders of magnitude faster
than the fastest disk.
\_ Try 5 orders of magnitude. Your point is still
valid, however.
\_ huh, isn't the disk access going to be faster at the outer
parts of the platter? look at the math, i degree of turn on
the inner goes thru less distance than on the outer edge.
\_ Aren't hard disk tracks concentric and non-uniform density
(the inner tracks have the same storage capacity as the
outer ones)? If that's the case, it shouldn't impact
performance either way.
\_ once again tho, how can you make sure that what cfdisk thinks
is "end" is what the mfr thinks is "outer edge of platter"
is there a standard to these things?
\_ That doesn't account for moving the head (which is the larger
source of latency anyway). Putting the swap near the center
means that you're more likely on average to swing the head less.
\_ this is pointless ... use the time and energy to buy more
memory or kill a unneeded application. if you are interested
in doing this to see if the difference is measureable well
then obviously you will have to measure for your hardware.
this might be an interesting way to see how good a
disk simulator is. --psb
\_ Actually, that was kind of my point. Making guesses this
deep without actually measuring the performance isn't
productive.
\_ WinXP automatically place it in the beginning 1/4-1/5 of your
partition. Not sure if that means anything. |

Thanks.

Great prices and out of state so no taxes. I had them build 2
custom boxes which showed on time and to spec with decent parts
on the unspecified stuff.
\_ http://newegg.com seems cheaper, maybe YOU should check it out
\_ Taxes, son, taxes. I know newegg and others. Also,
newegg isn't building custom systems which micropro will
do for you. I've done the math. On some systems you
can save as much as 10 bucks if you carefully order parts
from all over the net and then you still have to build
the damned thing. "seems cheaper" is not cheaper. Just
trying to give someone some help which you're not.

so how much more will I gain from using DDR2700 over DDR2100? Is
DDR2700 good only when the FSB is 166? This info is not on
tomshardware by the way.
\_ 2700/CL2.0/333 >> 2100/CL2.0/266 by 0-25% depending on how
memory intensive your application (game) is. If you're building
a top end system then get the 2700/CL2.0. If you're going to go
light on the cpu, video, or some other speed related part, then
save your money across the whole system and get 2100/CL2.5. |

\_ Won't help you much now, but you should really have
some sort of remote console access (terminal server
or serial cable) to non-local unix boxes. It's a
great help in situations like this. As it is,
unless I'm missing something, I think you're SOL,
unless there's a way to get the eeprom to recognize

\_ Not my box. Sometimes you gotta take what life
gives you and hope for the best.
\_ Make sure you're using an HVD SCSI card since D1000 is HVD SCSI
box.
\_ Hooked up to a single edged controller. The cabling exactly
matched another e450/d1000 pair I have that's working. I'm
thinking maybe the d1000 is just fucked. Running out of reasons
for this.
\_ HVD SCSI uses the same connectors as other SCSI
implementations. You could have plugged the D1000 into a
single-ended card. I'd double check the SCSI card chipset
and part number.
\_ I've got single edged scsi on addon cards which don't work
and tried the built in regular scsi. Nothing going on.
\_ The question is: Do you have a HVD SCSI card in
the system? Do you? --dim
\_ Yes. I'm desperate and trying things I'm sure won't
work bc I already tried everything I think should.
\_ HVD = High Voltage Differential as in NOT a normal Sun onboard SCSI
port. -ax
\_ Bent pin on the SCSI cable? SCSI Host ID's set to 0 or 7 on D1000?
Also, one bad disk can hang the whole SCSI bus and you will see
nothing. Finally, split the D1000 into 2 separate 6 disks pieces
using a terminator and no loop cable between the busses and see if
you can see either bus. -ax |

\_ STFW. google "dvd faq progressive scan" +"I'm Feeling Lucky".
\_ Progressive scan de-interlaces the signal sent out of the
DVD player. However, most TVs cannot handle a progressive signal
anyway, and displays that can are often of high quality so they will
have their own de-interlacer and scaler. Progressive just means
displaying the lines of the picture on the screen one after the other
going down, instead of first displaying all the odd lines in the
picture, and then the even for every displayed frame. Try setting
your computer monitor to interlaced display (if possible) and you'll
see how crappy it looks.
http://www.hometheaterhifi.com/volume_7_4/dvd-benchmark-part-5-progressive-10-2000.html

05/22 Any recommendations for a utility to totally erase a PC laptop
disk's contents. I'm selling my laptop and want my files etc.
totally wiped.
\_ Destroy the disk and grind it up. Only way. For those who
don't have top secret stuff, merely reformatting and filling
with emac dists will do just fine.
\_ There may be something better but one of the tools included with
PGP for windows is a wiper. It writes seven layers of random
bits over every selected file, as I recall. -- ulysses
\_ Would this naive approach be secure enough: re-partition the whole
disk to several FAT partitions then fill up each partition with a
single file containing 0xFF until the partition is full?
\_ if you're really worried, supposedly you can scan for variations
in gauss levels of each bit and tell if it was recently changed.
There are some government protocols for disposing of harddrives.
If you're this worried, though, i've got a bomb shelter i'd like
to sell you.
\_ I remember reading somewhere that data can be read off hard
drive that's been wiped(written random bits on) up to six
times, which is probably why the "wiper" program mentioned
above wipes it seven times.
\_ a layer of 0xff, a layer of 0x00, a layer of 0xff, ...
until you feel comfortable about the gauss levels mentioned
above.
\_ The above 'naive' approach is more than enough for a simple sale to
a private individual. In theory the data can still be recovered by
a professional data recovery firm that will charm thousands of
dollars with no promises of recovery. I'm sure the FBI,etc can
recover it though as they have essentially infinite resources but
I don't think this is a serious concern.
\_ what's wrong with just repartitioning the drive?
\_ Data is still there. Only partition and file tables are wiped.
\_ If you're so worried, why don't just keep your existing disk
and replace it with a cheap ass disk you can get at Fry's.
\_ for starters the 2" disk in a laptop is very expensive. !op
\_ and the time wasted in discussing all this is probably even
more than that.
\_ A 2" disk could run $150+ for even a smaller drive. I

They are unhappy that current law allows you to

to it as many times as you want and you can even

the RIAA. Same goes for movies.

far to extereme if the goal is just to stop
theivery. These measures are a modern sugar and
stamp act designed to provide the RIAA/MPAA with

I mean...wait for it..... "backed up storage".
\_ dumbass, where was your UPS? --Jon
\_ Buy two drives, and don't connect them to the machine
during normal usage. When you want to perform back up,
connect one and copy the files, disconnect it, then
connect the other one and copy the files, and disconnect.
Then when there's a power outage, you toast one drive as
most. It's a bit of trouble, but it works.
\_ If you really care about your data, you cannot
store you backups on magnetic media, esp. hard
drives. CD, DVD or MO is the way to go.
\_ Well, that's true. What's MO? What did people do
before there were CDRW drives?
\_ MO is Magno-Optical. MO has been around
for years, so have CDs.
\_ 5GB is a pretty trivial amount these days. Is this 5GB of
data per day or a 5GB filesystem? 5GB will fit on a DVD.
incrementals from a 5GB filesystem will fit on cdroms, easily.
You could even do snapshots to a large (cheap) disk as suggested
above. Why pay someone money to do something so trivial. I
could see it if you had 300GB of data for which you wanted
regular backups, but 5GB? --Jon
\_ 5gb? tapes are cheap for this size job. Then you'll have true
'backed up storage' just like you mean. I fail to see why this is
all so difficult for you for such a miniscule data set.
\_ Tape drives that wouldnt be total overkill for this (DLT or
AIT2 or VXA are overkill) such as say dds2, are pretty lame.
\_ Buy a DVD-R or DVD-RW drive. The A104 is ~ $400 , blanks DVDs
are ~ $3. For an outlay of $500 you will have reliable backups
that will last you years if not decades.

1/2 Anyone have any experience with USB 2.0 on Windows 2000? I'm
thinking of getting an external HD for my laptop and trying to
decide between USB 2.0 and Firewire. Thanks. - rory
\_ USB 2.0 comes included on some newer motherboards. Firewire does
not. Does your laptop already have FW support? USB2.0 support?
Do you plan to use this harddrive on any other machine?
\_ I have a Sony VAIO with one FW port and 2 USB ports. I
was under the understanding that USB 2.0 would use the same
plug. I thought the only hang-up might be software (driver)
support. I was hoping to use the HD on other machines, but this
isn't super important because I'm looking to buy a USB/FW case,
so will be using a standard IDE drive that I can always use
somewhere else. - rory
\_ It sounds like it doesn't matter. It was my understanding
that usb2.0 was hardware change but maybe a new bios flash
is good enough? I haven't researched it. It sounds like
you don't have a special need for either and should just
get the cheaper one. You should double check the usb2.0
thing.
\_ USB 2.0 requires a different chipset. I doubt you will be
able to upgrade your existing ports. I'd recommend you go the
firewire route, although I personally think firewire is the
better technology and that USB 2.0 is just a hack. You also
can look for enclosures that support both firewire and USB 2.0,
although that obviously will cost more. |

\_ Ever heard of region encoding? Basically, it prevents what you're
trying to do.
\_ buy a region-free player, hack your player to be region-free, or buy
a region 3 DVD player. if you have a DVD-ROM drive, you may have
better luck playing it on your PC. You can also try ripping it to
disk and decrypting it...
\_ Some PC DVD players let you choose the region. One I used
before (forgot which) let you switch regions up to three times.
Then you had to reinstall to change it again. |

12/29 I'd like to dip into the pool of motd wisdom. I'm going to buy a new
cd-rw. I don't have scsi so it should be ide. I want quality, speed
and the drive should be able to deal with any of the zillions of
standards. Price isn't too important but I don't want to take out
a second mortgage for it. What's the best ide cd-rw out there? Thanks!
(Please specify a model if you have one in mind or a product line)
\_ ? the most expensive CD-RW is about $200 these days. It's
a lot cheaper than you think. Any name brand drive will serve
you fine (and a lot of them are under $100)
\_ I think these suckers are almost a commodity now. HP is well
spoken of, but I've been satisfied with my Sony CDRW. It cost
about $100 when I got it. It does 8x CDR, I forget its other
speeds. I've gotten it to work under Linux with minimal trouble.
\_ LiteOn 24x10x40 has worked well for me and my friend. Paid $81 for
it. http://tomshardware.com has a recent review of IDE drives. In brief,
every drive is full featured except some Sonys.
\_ Apparently it's been a while since you purchased a CD-RW drive.
They're universally cheap. They're universally compatible. IDE
sucks much less than it used to. Probably the best drive
available on the market today is TDK's 24x velocd:
http://www.tdk.com/velocd-new/24index.html
Should cost between $150-$160 after tax/shipping if you shop
around. Comes with a solid software bundle (but you don't care
about that if it's going into a non-windows machine). They've got
a 32x burn model coming out if you're willing to wait, but it will
probably go for a premium for a few months after release. If you
are cheap, get the LiteOn, it's a damn good drive for the money.
If you want the fastest thing under the sun, get the TDK. It's
excellent, and still pretty cheap. -dans
\_ "...it's been a while since..." Actually I've never bought one.
I bought a retail 24/10/40 plextor for $148 - $30 rebate. It
looks pretty much the same as the TDK except has a 4mb buffer.
I don't know if that makes a difference but it's cheaper and
specs out the same otherwise. I can't wait for a 32x to come
out. I need it in the next week or so. Thanks to both of the
above for URLs and your helpful comments. Sometimes the motd
works.
\_ Plextor good. Plextors have been and continue to be the
Cadillac of CD-Rs... except in a good way. |

\_ TDA disks are less than 9GB each, so you need a disk array
with about 10 disks in it to backup your 80GB HD? How's your
PG&E bill?
\_ Wonderful. It's no surprise PG&E is bankrupt - they've
determined they owe me $150 for the power I've used for
the last six months that I paid nothing for. Must be
ultra-new math.
\_ After they figure it out you'll get billed plus

\_ C'mon. 5.25" floppy disks are too small for the job. I use the
bigger 8" floppy disks.
\_ My cp/m machine doesn't boot anymore and the disk drives

10/27 Does Linux or BSD support CD to CD (I have a SCSI Plextor) burning?
\_ Not that I know of. I think you're best off reading the CD
and then burning it.
\_ Nothing prevents you from doing dd if=/dev/cdrom | cdrecord ....
or cat /dev/cdrom | cdrecord ....
\_ Have you actually tried this or are you just assuming this
should work?
\_ Dunno about BSD, but the Linux CD writing Howto claims that
this is not possible for audio CDs:
http://www.linuxdoc.org/HOWTO/CD-Writing-HOWTO-4.html#ss4.7
\_ The author of cdrecord suggests using readcd instead of dd .readcd is
part of the cdrecord distribution. dd can't handle some special
cases. It should be as simple is
readcd dev=0,5,0 f=- | cdrecord ..
which a correct dev option, though, I am not sure how reliable that
is ..

constructed, it can rattle ...
\_ [again] Your fan is integrated into your PS. Your CD/DVD,

10/1 (Can someone please re-post any response? I think I'll start running
my own motd auto-archive from now on.)
What's the minimum CPU requirement for Win98 (ignoring speed)? I have
a Pentium-something 133MHz machine that has been running Win95 fine.
But when I re-formatted the disk and tried to install Win98, it always
hangs at about the same point during the installation process when it's
copying lots of files from the CD. I'm guessing it's trying to execute
some instruction that's not supported by the processor.
\_ have you tried running the install files directly from the HD? I've
installed Win98 on Pentiums before with no problems.
\_ You mean copying the whole CD to the HD, then running
installation without the CD? No I haven't tried that. I don't
know if the HD has enough space to do this. But I can try. But
how do I copy all the files from the CD when I don't have
anything to boot from? And why does installing from the HD make

\_ I heard that cheap ones can't play CD's you burn yourself. It's
something about the format on those CDs being different from that

Some DVD players have two lasers. The ones that don't usually
can't play CD-R. Of course, that's what CD players are for.
Most Sonys can't player CD-R. Pioneer can. YMMV.
Most Sonys can't play CD-R. Pioneer can. YMMV.
\_ Why does it need two lasters to play CD-R but only one to

\_ Or one laser that can do dual wavelengths. Many players
use a laser that is a compromise between DVD and CD
wavelengths to read both. Factory pressed CDs are more
conducive to this laser (reflectivity), while CD-R is not.
\_ I see. What about CD-RWs? Do DVD players with only one
laser wavelength have the same problem with CD-RWs?

\_ Make sure you get a SCSI PC Card supported by your OS.
Alternatively, if you have a swap-out CD-ROM drive,
your laptop manufacturer might have a CD-RW drive

select a hard drive is it's noise level. Seagate's new
Barracuda IV is the new champ (as soon as you can actually
*buy* one, that is) at 2.0 to 2.4 bels. If you can't wait,
then Samsung makes some that are in 3.0 to 3.1 range.

the moral is to not do stupid things like leave cd's
in direct sunlight etc. no matter what kind it is.
\_ Gold costs more to manufacture and has a better
shelf life in spite of the fact that silver does
have higher reflectivity. Most unbiased sources of
information do in fact tout phthalocyanine dye as
the best. Personal experience with it is also very
good. If you read the claim on the URL you produced
you will see that they claim superiority based on
"lightfastness". That is an advantage, but not the
whole story. Dyes other than phthalocyanine "move"
during the burning process. In short, there are
advantages to each dye but for archival (stored in
the dark in a controlled environment) you want
phthalocyanine dye and a gold reflective layer. --dim
\_ hmm, I'd be quite interested in seeing one of these
unbiased sources for myself. in my travels such
things have been rare.
\_ Do a search on the web. --dim
\_ Do a search on the web. Sandia Labs did a
test. MIT Library decided to go with gold
phthalocyanine disks (Kodak). JPL is using
the Mitsui disks I mentioned earlier based on
experience. Here's another study which touts
phthalocyanine disks:
http://ikrweb.uni-muenster.de/aptdir/aktuelles/arc
hivmedien.html . Believe what you will. --dim
hivmedien.html says "After aging, two media
types were completely unreadable--Taiyo Yuden
and TDK. These manufacturers use a cyanine
dye, which is less stable tha[n] the
phthalocyanine dye used by other manufacturers."
Believe what you will. You know best. --dim
\_ Andy McFadden's CD-R FAQ has a section on media:
http://www.cdrfaq.org/faq07.html#S7 -tom
\_ Well, I've had no problems with anything except those "gold"
noname ones. One of those with my personal files on it
stopped being readable one day. But the weird thing was,
I kept it anyway, and months later tried it and it worked.
I've had good results with Imation and Kingston (phthalocy.)
but recently have been using Verbatim (blue azo) without
problems; azo is claimed to be as good as the gold/platinum
etc. but time will tell. Regardless, another possible issue
is: Did you write on the disc, and if so, using what?

5/28 A year ago I backed up my home dir onto a CD-R. Afterwards I tried it
on a regular CD-ROM and all the files seems ok. Now when I try to
access it it complains about a corrupted directory structure? What
could cause this to happen? Bad CD writer or bad disk? And is there
a way to recover from this? Thanks.
\_ If you backed it up on a CD you must not have cared about it. I
suggest you ditch the coaster and move on with your life.
\_ CD-R's are fairly reliable, certainly more so than most tape
media. What do you do your backups on, troll? They are
susceptible to scratching, particularly if you write on the top
surface with a ball-point. They can also theoretically degrade
over time, but they still should be better than most tapes.
Have you tried it in different drives? Sometimes a particular
drive and a particular CD won't get along because of vibration
or other issues. -tom
\_ The other major problem with CDRs is that they are
exteremely sensitive to any sort of light. You can't
leave them lying around exposed to overhead light
or sunlight and then expect that they will work.
If you need reliable backups, I would suggest MO
or a external harddrive.
\_ hard drives are many orders of magnitude less
reliable than CD's, even CD-R's. -tom
\_ An unpowered external hardrive will last
years as compared to the life of the ave.
cdr which is less than a few months. MO
is the way to go if you *really* care about
your data.
\_ MO is good (and recordable DVD is a
successor to MO, not to CD-R). But CD-R
is pretty damn reliable; manufacturer
claims are for 75 years, and I've never
had a burned disk go bad on me. Burning
failure rates are fairly high, but that's
not a longevity issue. -tom
\_ I'll bet you burn your CDRs and then
put them in a cool dark place unlike
above poster.
\_ The back seat of my car in the
parking lot doesn't count?!?!
\_ Would you trust your data to one burn on a CD or the
typical 0/5/9 tape cycle where your data is likely to hit
tape multiple times and probably get a copy stored off
site? I'll keep my stuff on tape, thanks. It's easier to
manage, holds more, and less likely to result in a motd
post about "how do i get my stuff off this fucked up tape?"
Maybe you can explain why tapes are still in use if CDs
make superior backup media? Everyone else must just be
stupid, huh? In this case, he might get lucky and find out
it's just a CD device incompatibility issue, but then
again, maybe not. I prefer to avoid "luck" with my data.
\_ The issue of the reliability of the media is
completely irrelevant to whether there's more than one
copy--you can do 0/5/9 with CD, too. Are you really
doing multiple-level tape backups with off-site storage
for files on your home machine? Of course not, you're
just trolling. And I didn't say CD's make superior
backup media, I said they're more reliable than tape.
The limited size makes CD not useful as backup for
shared filesystems. -tom
\_ More than one copy *is* important. No one cares about
media reliability so much as they do about getting
their data back. If one media type is slightly more
reliable than another but I have 6 copies on the
lesser media type, my odds of getting my data back are
better with the 6 copies on lesser media. Tell me
you've got 3+ copies of each CDR?
\_ He didn't say it was a home machine. He said it was
a "home dir" which is an entirely different matter.
And yes, it's easier to do 0/5/9 with tape than CD.
No, I don't do any backups for home, per se. Files I
want to keep get tgz'd and copied to work where I do
incrementals/fulls/offsite. But, oh yes, I forgot,
anyone who disagree with tom is automatically a troll.
\_ Interesting... what media do you recommend for backup
of a home system? (FWIW, right now my main strategy
is rsync of what I care about to several computers.)
--Galen
\_ the vast majority of home users don't do backups at
all, so if you're doing anything you're ahead of
the game. I use CD's but if you have another
system that's probably fine too. I just think
the first response was horribly ignorant. -tom
\_ He never said it was a home system. Read it.
\_ Dude, guys, is all that porn really worth the backup?
\_ hell yeah. building up a good pr0n collection takes a
lot of time and effort.
\_ I'm with Tom on this one. -ausman
\_ Yup, that settles it. This from the guy who has
trouble reading a dictionary and projects this
reading problem on others. With friends like that..

5/11 top shows a lot of "io wait" How do i find out which processes
are doing all the disk writing/reading? and is there a way to
"nice" a process with regards to disk io the way nice does for
cpu utilization. (if not, shouldn't there be?)
\_ Some versions of ps will do this with the right options. |

4/17 Now that those rat bastards at VALinux are getting out of the
desktop market who is a reasonable alternative as a supplier?
IBM? HP? Dell? Someone else? --dim
\_ what was good about VALinux? there's penguincomputing.
I don't know why you'd care, just install Linux on anything.
\_ Just say no. If you must
use PC hardware, at least
install FreeBSD. \
\_ and deal with freeBSD? fuck that.
\_ Deal with what? You're either
a troll, ignorant, or simply
deeply confused.
what's so bad about PC hardware? it's cheap and fast _)
hey, this is a good troll.
\_ BIOS, crappy memory bandwidth, floppy disks, IDE drives,
32bit PCI, ISA, bad power supplies, awful SMP performance.
I don't think that I need to go on.
\_ You do realize you can buy a PC with SCSI and PCI64,
right? SMP performance is partly a function of the OS.
Have you seen what kind of crap Sun is shipping these
day? Their low end boxes are IDE! --dim
\_ Sun is shipping this bottom-end server crap, the 280R:
redundant hot-swap power supplies with independent power
cords, hot-plug power subsystems, fibre-channel disk
drives, backplane has software-mirrored hot-plug boot
drives. 8MB cache. 8GB RAM. lights-out management card.
Free solaris. Now hook it up to the T3 external hardware
RAID array, GBIC cards, dual-ported 10K RPM FC-AL disk.
Max. multimode optical fiber length of 500 meters.
Two redundant loop cards per enclosure FC-AL circuitry
Two Power/cooling units per enclosure, Integrated
backup battery power, Redundant fans, Battery backup
for cache destage. Free Veritas. Yeah I agree its shitty
product. But your cheap PC will always be its bitch.
You can mass your million-man Red Army, but their few
precision jet bombers will blow you to bits.
So what if their products "suck", I'd like to take a poll:
if SUDDENLY TODAY, someone gave you choice of a FREE $1000
PC or a FREE $1000 SunBlade, which one would you take?
\_ VA Linux sales were good at calling over and over and over
like clock work. I always knew it was the first thursday
because that's when VA Linux sales would call.
\_ the SunBlade is a piece of shit. The 280R, configured
with 8GB of RAM and a T3 RAID array, costs $90K,
hardly "bottom-end". -tom
\_ You are nothing more than a shill for Sun. -ausman
\_ No, that's the top-end E280R configuration.
I just priced a $10,000 one on their site
(one CPU, one disk, etc..)
\_ A $1000 PC is a POS. A Sun Blade is not. I'd
take the SunBlade over even a $10K PC.
\_ The 280R *is* the bottom-end of the Sun server line.
It's a workgroup server. Max two CPUs only.
\_ are you stupid or just lying? The bottom-end
server is the Netra X1, which costs an order
of magnitude less than the 280R, and is a piece
of shit. -tom
\_ are you comparing PC servers to desktop machines? --jon
\_ Ultra 2, 2 300 MHz US2 Procs, 1GB Ram, Creator 3D
now that is a Desktop Machine (~ 2 - 3K now).
Or an Ultra 60.
I prefer real hardware to some cheap broken PC
crap.
\_ An Ultra 2 is a piece of shit these days. --dim
\_ Really? I guess that the 2 GB of RAM
it supports along with the 2 300 MHz
US2 procs are just no good compared
to your OC'ed Celli 933s. I'm so sorry
that your IO bandwidth and your memory
bus speed SUX, as does your SMP bus.
But I'll bet your GeForce2MX make up
for that in your "real world" applications.
\_ PowerMac G4 w/2x533 G4e's, 1 GB Ram, Ultra 160
drives, GEForce2 (or 3). Now that is a desktop
machine.
\_ P5-166, 96 megs RAM, 3 EIDE disks: 1.2 GB, 2.0 GB, 4.3 GB,
Matrox Mystique (the first one), OpenBSD, open air case,
300 watt PS, 1.44 diskette, 2 serial, 1 par, dual 10/100.
Rock solid! Top that, kids!
\_ SparcStation 10, 1 SM61 proc, 272 MB Ram,
2 Barracudas, QFE, no framebuffer (serial
console only), OpenBSD CURRENT.
\_ p5-166?
\_ Dell makes rather nice Linux boxen. Don't expect their
Linux (software) support to be anywhere as good as VA Linux
though.
\_ Are you joking? My research group ordered some computers
from Dell and they SUCK. We ordered the plane vanilla
machines with Linux pre-installed and Dell installed
unsupported video and network cards then dragged their
feet when we asked them to fix there mistake. I will
never again by Dell.
\_ VA has support? Surely you jest.
\_ VA Linux sales were good at calling over and over
and over like clock work. I always knew it was the
first thursday because that's when VA Linux sales
would call.
\_ I said support. |
