There used to be a nice piece of hardware/software for testing Amigas as well. I can't think of the name of it, but I'd look into it if I were you.
Commodore had a 'systest' disk that was usefull for stress testing intermittant problems. They also had a diskalign program for floppy drives, but this required a special disk with alignment patterns written on it. I used it a couple times, but it was usually better to replace the drive. Nowadays, that might be more difficult. :-)
