Joe is right that an under performing power supply can lead to these
sort of problems. If you've recently made any hardware modifications
to the box, especially adding extra new bits, then that's a distinct
possibility.
However, much more likely is that your hard drive is developing a
fault. Moving parts wear out, and hard drives can be quite fragile,
especially if they have been used heavily or are running at high
temperature. (If you've maxed out an ordinary tower case with hard
drives, then you really should think about adding extra fans to
improve the air flow. Server class or rack mount kit is usually
designed to cope with the extra drives already.)
First of all, make sure you have good backups. That disk could give
up the ghost at any moment. Make sure the machine is adequately
ventilated, that all the fans are working and that any vents are not
clogged with dust. If that doesn't make things any better, it's time
to get out the screwdrivers and start swapping out the suspect
components.
Cheers,
Matthew
