Someone pointed out that the 3B2's disk may still be salvageable. I'm not sure
about that, but I don't have a lot of
experience with the older drives. It's probably the original disk, as it has AT&T
stickers on it. Plugged into multiple
computers and external drive enclosures it spins up, head load click, then spins down.
I've tried reseating connectors
and checking jumpers, no change. I don't know what the jumper on the bottom side of
the lowest PCB near
the SCSI connector does, and there are two empty DIP sockets on the bottom of the drive
that could possbly be a
part of the problem. I haven't taken a scope to it to trace out the signals yet and
see if an amp died.
