At the risk of angering the gods, do you have access to a Windows
system?
There is a test program that I have used that seems to be an extensive
test program.
It comes from IBM/Hitachi and is called a "Drive Fitness test". They
request you run it before asking them for help with a disk problem or
before returning a disk because you think it is defective.
You can find it at: www.hgst.com/hdd/support/download.htm
One added note from experience, the drive test may check out but the
drive could still be defective. I replaced over 200 disks, probably over
300 by now for the 2.5 inch disks.
Check on the hard disk controller to see if there is any coating on the
printed circuit board of the hard drive. It looks either burned or
corroded. Anyway it will be obvious to the visual inspection.
These disks were running w2k as the OS and the disk checking program
never flagged the drives as bad. The program might be improved over what
I saw in the past.
We no longer use the IBM/Hitachi disks and failure is at least 50% less
failures than before concerning hard disks.
Not a knock on IBM/Hitachi disks in particular since we ran them in 24/7
operations before switching to another vendor.
