smartctl. You may have to install the smartmontools rpm (from the base
FC4 repo).

Run
smartctl -l error /dev/hda
as root: you may need to run
smartctl -s on /dev/hda
(that's all one command to be run as root).

Also try
smartctl -H /dev/hda

smartctl -t short /dev/hda
which will do a low-level check on the disk: wait a minute for that to
run, then do
smartctl -l selftest /dev/hda
to see the results.

Fairly obviously, this assumes that the drive is /dev/hda.

Also go to
http://support.wdc.com/download/index.asp?cxml=n&pid=999&swid=30
and try the manufacturer's tools.

Also try memtest86 (on the boot CD). Seriously: this looks like dodgy
memory.

My sigmonster's being sentient again.
