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.
