I had a similar problem with my Priam ID100 (RLL certified version of
the ID60).  However, in my case, it turned out to be intermittant
op-amp's on the disk-based pcb linked to the pll spindle speed control
circuit.  Replacing the op-amps permantently fixed the problem.
However, what was interesting is that whenever I'd take the drive out
to see if I cound find some mechanical problem, and reinstalled it,
the drive would work again.

Don't know if this will be any help.
