I have tried a number of things, including what's described at the bottom of this web page (taping a pin): http://nemesis.lonestar.org/computers/tandy/hardware/storage/mfm.html As far as 225's go, so far I have not had any luck. It may simply be that I have had bad 225's. I have also tried other similar drives. There are a lot of messageboard/usergroup posts about substituting the Tandon drive on the D9090. In short I thought that if anyone had an actual Tandon 603s or 602s it might be this group, does not hurt to keep trying! I have pretty high confidence that the controller and power supply are OK, all the diagnostics I can perform indicate that these components are healthy. The 603s that I do have almost works...The drive actually gets a few clicks into the formatting before getting a drive error. Theoretically you do not have to do anything to the drive if you swap a 603s for a 602s. If you use a 602s, you in effect convert a d9090 into a d9060, and the capacity is reduced to 5MB. Thank you for your replies.
