Have you tried to completley dismantle the RC50? After that the 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
or heads. The RX50 seems ot haev been desinged so it's almost impossible
to alight -- you can't get to the stepper mounting screws when the
seek/interface PCB is fitted, conversely you need this fitted to runs the
drive. I have a LART resereved fro the 'genius' who came up with that one...
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
at least three different hardware revisions, to fix various problems --
like the unreliability of some, hence the screening and rules about
grounding it.
