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.

1/4     I want to test how my servers behave during a disk failure and
        a RAID reconstruction so I want to simulate a hardware failure.
        How can I do this in Linux without having to physically pull
        a drive? These disks are behind a RAID card and run Linux. -ausman
        \_ According to the Linux RAID wiki, you might be able to use mdadm
           to do this with something like the following:

9/13    Thanks to Jordan, our disk server is no longer virtualized. Our long

        another long nightmare of poor hardware reliability!

2/14    You sure soda isn't running windows in disguise?  It would explain the
        uptimes.
        \_ hardly, My winbox stays up longer.
        \_ Nobody cares about uptime anymore brother, that's what web2.0 has
           taught us.  Everything is "stateless".
           \_ You;d think gamers would care more about uptime.

7/22    Playing with dd if=/dev/random of=/dev/<disk> on linux and bsd:
        2 questions, on linux when <disk>==hda it always gives me this off
        by one report i.e. Records out == records in-1 and says there is an
        error. Has anyone else seen this?  Second, when trying to repeat this
        on bsd, <disk>==rwd0 now, to my surprise, using the install disk and
        selecting (S)hell, when I try to dd a 40 gig disk it says "409 records

8/3     VMWare + Windows XP + Validation question. I need to test stuff with
        Service Pack 3 installed. I have a valid key that I own (yeah yeah I
        actually *bought* a copy, please don't flame me for supporting evil
        M$). Is it possible to register the key once, and then duplicate it
        for testing purposes?  Will Windows or Microsoft detect copies and
        disable the rest the copies?

7/28    Does it make sense to defragment disks on VMWare? My 80GB disk
        on VMWare isn't really using 80GB, it just uses what it needs.
        Will defragment do anything to it?
        \_ If you want to speed up disk operation in your VM, it's best to
           defragment the disks in your VM, then defragment the disk on your
           host machine where the VM files are.

7/24    Firefox 3.5.1 on MacOS is a piece of crap. It crashes ALL THE TIME.
        It has crashed 3 or 4 times on me in the last hour, and not on
        the same pages either. The new Yahoo! home page also sucks ass.
        \_ os x keeps trashing my raid disk: '11 hours to rebuild. have fun
           with the kernel IO subsystem running like shit until then".
           Worthless piece of shit.

        What does the "at sign" mean? This is on Mac OS. VMWare disk file.
        \_ The file has metadata attributes
           \_ How do I add/delete attributes to files? What about
              -rw-r--r--+ <-- what is the "+" sign? Also how do you make
              tar preserve these attributes?
