I wouldn't be so sure that the spindle motor is still okay. Did you try to exchange the spindle motor control PCBs between the two drives? I had a spindle motor problem on a 8250, the control transistor was running hot and the drive wouldn't come up to full speed. It was a spindle motor problem, opening the motor and cleaning the contacts helped. Obviously carbon residue was sitting between the contacts and causing some sort of short circuit.
