I would vote for a damaged/shorted PRE-AMP (inside the drive) requiring (expensive) clean room work.

Are the motor windings of equal resistance, approximatley 1 ohm?

Between any two pins of the motor it has to give the same resistance of just 1-5 ohms (the reading will vary depending on the motor and the calibration of the multimeter) ..

The fact that the drive didn't spin ruled out bad rom code or bad pcb.
Unless the drive have bad spindle or stuck heads (not very likely) i would say that the pre-amp is gone ... Either is shorted preventing the drive from spin or the ROM code does check for pre-amp version, can't get any reply from pre-amp and refuses to start/go further on the code making the drive not to spin.
