Re: Problem with my HDD

[Billy Transue <bill@black9.net>]

Thanks, I had no idea it allocated all the space right away, but it
still didn't work, the file got a bit bigger, not much.  It was 
73728 bytes big, I let the process run til my computer suddenly crashed,
here is an excert from syslog, there was ton of lines just like the
first 3 shown, from 12:01 til this last one then the kernel panic.  It
should be noted I've been getting kernel panics before too.  I think my
2nd chip of memory is bad.  I'm taking it out after I type this,
hopefully no kernel panics til then.  Any advice?

May 31 12:19:09 threshold kernel: hdd: read_intr: status=0x59 {
DriveReady SeekComplete DataRequest Error }
May 31 12:19:09 threshold kernel: hdd: read_intr: error=0x40 {
UncorrectableError }, LBAsect=11310269, sector=446
May 31 12:19:09 threshold kernel: end_request: I/O error, dev 16:45
(hdd), sector 446
May 31 12:19:14 threshold kernel: CPU 0: Machine Check Exception:
0000000000000004

Love,
Billy
