One serious
issue with the diskette drive: It has one or more "dead"
spots in its rotation. If it stops at such a point it fails to spin up
again at the next access. When it spits the diskette out with an error, I
give the spindle a small push with a screwdriver, reinsert and it picks up
from that point.
Hopefully folks have some sage advice for dealing with dead spots? It's
not related to the excess pressure on the head - it doesn't even try to
spin. There's absolutely no sound or activity.
Interesting. This sounds liek a stock fault with these Lisa drives, I
think Terry had much the same problem. I wouidl be interested to hear if you manage to repair
it.
Since the drive in the second unit works correctly, I'm probably not going
to spend any time on it. There's plenty of work ahead replacing all the
wiring harnesses and cleaning the case and chassis.
If someone put one of these balky drives in your hands, would you have any
interest in tinkering with it?
