So you have a RAID 1 external combo.
FWIW: Every hard drive...has some bad sectors, with the only variable being whether or not the user places files on such. You might read the comments of rforce at http://www.tomshardware.com/forum/245985-3...ors-brand-drive
, just for GP.
So your RAIDed drives are still susceptible to possible data, program, or O/S files being placed on bad sectors.
The common way that I check is via chkdsk /r. If chkdsk /r cannot take care of it, I go to the manufacturer's diagnostic for opinions on the health of the drive.
So you have at least 4 hard drives which it probably only takes one of them to be suspect...to cause a potential problem, IMO.
If you insist that you "know" it's not "the" hard drive, then...I really don't know what to suggest other than a corrupted folder or bunch of files. AFAIK, the best way to check for file corruption is to run chkdsk /r from the Recovery Console, command prompt, or My Computer.
