Anybody got any experience with an HD20? (the original non-SCSI hard drive for the Mac). I just got one that won't mount (asks if I want to initialize the disk). The HD20 Test indicates that it does not pass the self-diagnostic. I don't want to see if I can re-initialize it yet in case there's some good software on it. Plus if it fails the self-diagnostic, I may not even be able to initialize it. Anybody know why it would fail and what steps I can take to repair it. All other indications are that it is in good shape.
