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.
