I'd stress-test the drive. I use a lot of old hardware so have this
down pat: boot with a live CD (I use grml) on boxes that boot CD, and a
custom boot set (based on Woody) for older boxes that only boot floppy.
on one VT, run e2fsck -c -c (the double -c causes it to do a slow read
write verify bad-block test so that each sector gets read and written).
Do this for each filesystem you have.
On another VT, run tail -f /var/log/syslog and watch for drive errors.
If all goes well, reboot the system and do a long smartclt test and see
if the drive has recorded inordinate errors. Also check the drive temp
after all that activity.
Remember, a SMART error is a good indication of a problem, but the lack
of a SMART error is not necessarily a good inidcation of a lack of a
problem.
Doug.
