3/5     Can a PC boot from external (usb or ieee-1344) hard drives?
                                            \_ did you mean 1394?
        \_ depends on your bios support.  Quite a few now can boot from
           external usb-anything
           \_ If you're trying to boot XP, look for Bart's PE Builder.  For
              a USB-bootable Linux, have a look at
              I have another one lying around somewhere, so drop me a mail
              if you want me to dig for it.  -John

11/12   how do i make a fail safe magical backup for my debian box
        that i can quickly boot from if the box explodes?
        \_ keep a linux live boot cd around for just such an emergency
           \_ And learn about 'dd'
        \_ I was hoping there was something as slick as CCC, for unix.

12/29   A friend's primary Windows 2000 hard disk got nuked, and her
        backup drive is missing data. I'm looking for any
        recommendations for data recovery software for FAT/NTFS
        (restoring deleted files or corrupted filesystems) or
        recommendations for data recovery services in SF?

12/27   I'm trying to help out with my mother in law's computer problems. She
        has two Windows XP computers (one desktop, one tablet pc) that she was
        using for her job before she retired. The computers themselves are old
        and her workplace doesn't want them back but they are installed with
        all this corporate Novell stuff that I don't know anything about and
        her account on the computer has very restricted permissions (she can't

6/22    When I burn an iso image using the "Disk Utility" in OS X (Tiger)
        and I then use readcd on a linux box to verify the md5sum of the
        burned cd, the md5sum of the CD doesn't match the md5sum of the
        origional iso file. Is OS X modifying the iso image before it
        burns it or something? Seems strange.
        \_ Does this match on any of your other burned-CDs vs. ISO files?

5/17    My second data backup question. I am looking for a backup media I can
        take off-site. I'll repeat that we've found the failure rate backing up
        to CD unacceptable. She wants to go with an Iomega product but I was
        wondering if people have had good/bad experience with these,
        reliability-wise and if they have better suggestions. I have about
        $400 for this.

4/1     I'd like to play my favorite EA game on the laptop. However, I
        don't have a CD player for my laptop and I'm wondering if it
        is possible to mount the CD on my desktop and access it via
        wireless. I know that EA has really weird CD protection
        schemes, that's why I'm wondering if anyone has successfully
        done this. -ok thx

3/19    Given the choice between a firewire and USB2.0 connection
        (between an external hard drive and my computer), which one is
        better and why? Thanks.
        \_ Firewire is faster and more robust for that application.  USB
           is more widely available if you'd ever want to move the disk to
           another machine.  -tom

2/23    Hi, my girlfriend's mom is in Taiwan.  Her computer stopped booting;
        it shows BIOS, but it won't show the WinXP screen.  So, it sounds like
        a virus (less likely, partial drive failure / OS corruption, but let's
        assume it's a virus).
        She is concerned about recovering her files.
        Normally if I were on-site I'd just pull out the drive, put it in an

2/3     So, I'm really confused about this notion of computer science
        metrics where everything's kind of 2^n, but sometimes not. For
        example, if I have a 4 GIG hard drive, does that mean I have
        exactly 2^32 bytes of space? Does that translate to 4000000000
        bytes, or some number that's close to it? How about megahertz?
        Say I have a 2.5GHz computer, does it run at exactly 2500000

1/18    A bunch of CD-ROMS I have are corrupted. They're in a nice
        CaseLogic case, closed, stored in a temperate (70-85F), dry
        location. I have no idea why they're corrupted, but I know
        one thing-- they've been sitting close my Sharper Image Ionizer
        [plus UV mode turned on], for maybe 6 months. I'm suspecting
        that either the ions or the UV killed them, but is it actually

1/11    Using SATA (serial ATA) as the one and only primary HD, any
        problem with boot up? How about with motherboards built in say,
        2002? Any problem with that? Pros/cons with SATA? Comments?
        \_ You expecting to install Windoze on SATA and have it boot?
        \_ I had to get a special driver floppy to install Win XP on a recent
           box w/ onboard SATA.  It wasn't too hard, though.  YMMV.  --dbushong

11/12   Dual boot question:  I had a hard drive set up with dual boot.
        XP and Linux.  I had problems with the Windows partition.
        I got a new hard drive.  I connected the new hard drive and set it
        as the slave drive.  I went into setup and set it to boot from the
        slave drive (the new one).  I then reinstalled XP on the new drive.
        Oops.  My boot loader on the original drive got overwritten.  The

Reply with quote Hello Everyone, I'm new to the group, but not to Unix. I've been involved with it since t he early 80's, but haven't used it consisently since then. After a bit of tinkering and looking thru source code, I have successfully been able to boot Knoppix 36 from a 512MB Sandisk cruzer US B key. I want to document the complete process because I know how many of you ar e interested in doing this also. Reply with quote Well it's late and I wish I could do this in more detail, but this is the best I can do for now. I also want to give credit to the other people who've done this with previous versions because it was their info that helped me come up with my method. This is just a draft, and with any version of Unix, there are always many ways of reaching the same results. Next format it with "mkfs vfat" Now mount your flash drive and copy the contents of your remastered version of knoppix from your CD or ISO file so that will fit in the capac ity of your USB flash drive. "cd" to the /boot/isolinux directory and "mv" everything up to the root o f your flash drive and remove the whole "boot" directory. The linuxrc file is slightly different than described in the link in my previous message, but I don't have time to verify any changes I *might* have made. zip" for windows You'll of course need to boot up windows to run the program. The syntax would be "syslinux x:" where "x:" is the drive letter windows sees your flash drive as. I've had to change the 1st boot device in the BIOS to "USB ZIP", it may be different for you. I've only been able to test this so far on an VIA Epia Mii 10000. A couple of times I've gotten to the point where the penguin shows up in the top left (This is just before the "linuxrc" begins executing), and got a "kernel panic" because it's unable to mount the root filesystem and the system halted. I've rebooted and tried again and things started r ight up. I've also tried just typing "knoppix 5" at the boot prompt (whi ch is default anyway) and that seemed to give it whatever delay or encourage ment to work also. I hope this will be enough of a guide to help some of you continue and maybe iron things out a little more by the time I return. At that point I'll be happy to write a How To with explicit detail and directions and add any improvements any of you may have. The BIOS doesn't even recognize the USB drive a s bootable, which seems really weird. I don't think it is a hardware pro blem, because this is a 1 GB PQI iStick. I can boot Damn Small Linux no problem from a smaller PQI iStick on the same Epia ME6000 motherboard. FAT32 filesystem instead of FAT16, and I ran syslinux 211 from Knoppix, not Windows. Reply with quote I'm in a little bit of a rush right now, but I hope also post a message w ith the boot process and messages you should see at each stage. jbreiden, you're right, I don't think FAT32 vs FAT16 should matter, but . I sounds to me since you've been able to boot DSL off your stick, that you're not even getting SYSLINUX to go yet. Are you getting any msgs to indicate the boot process from your stick has started? If you can get that, you're headed in the right direction.... I don't expect to have net access while I'm gone, but if I do, I'll check back. Reply with quote You are right, it doesn't even get to syslinux at boot. The problem seems tied to this thumb drive, since others work. Maybe my motherboard can't boot from USB2 devices, only USB1 (I should look into whether there is a BIOS upgrade). Or maybe there is something special about the 1GB PQI i Stick or how it lays out the tracks/cylinders or something. I tried file system type 6 (FAT16), I tried making the partition smaller (511MB), I t ried syslinux 204 and 211, I tried giving the -s flag on syslinux /dev /sda1, and I tried marking the partition bootable and non-bootable. Reply with quote I have a Toshiba Sattelite 1805-S274 and I just bought a 128 MB Transcend Stick USB 20 Can anyone help me get it to work on Knoppix. My Hard d isk controller has crashed and I have to use Knoppix. I have alsready formatted it on a Win98 and have t ransferred some files on it. Do es anyone know how to get my Notebook modem to work under Knoppix. Reply with quote drmarathe wrote: My Hard disk controller has crashed and I have to use Knoppix. Assuming you're running Knoppix from the live CD: plug the USB key in and boot Knoppix. Knoppix will automatically show an icon for it on the des ktop. From the context menu, you can mount it and change its read-only s tatus to read/write. Assuming you're running a hard disk installation of Knoppix: plug in the USB key (it shouldn't matter whether it's before you boot or after KDE's up, since Knoppix uses "hotplug"). As root, in a console, type mkdir /mnt/sda1 mount /dev/sda1 /mnt/sda1 and you should be good to go.
