Does the Disk Utility show a S.M.A.R.T. status for the drive that is problematic? I have noticed (using my G4/500 system for video/audio) that I have had 2 drives fail over the past 5 years (one WD one Maxtor). The SMART status should tell you if the drive is feeling ill. If the drive does not support SMART, then you might want to assume it is going bad and replace it to be safe. The only other option is to go to the manufacturer site and download their WINDOW based diag utils that you can interrogate the disk and see if it failing mechanically.
