R/W and spindle motor PCBs come off trivially. So does the
belt, the spidnel motor and the hubs. But don't touch the stepper motor

Yes, there's a special test rig to do it. No, I don't have one. I think they are the most awful floppy drives I've
ever seen. There are
I've seen much worse. Ones built on a plastic chassis for example.
at least three different hardware revisions, to fix
various problems --
like the unreliability of some, hence the screening and rules about
grounding it.
When I got mine working, it seemed pretty reliable actually.
