     If the drive is otherwise working normally (i.e., disks can
be correctly read and written), I suspect a failed-on disk presence
switch.  Usually it it's an infrared emitter-detector pair; when the
beam is interrupted it means a disk slid in to break the beam.  So it
would suggest that either the emitter or the detector has failed.

     Does the drive ever stop running after a disk is successfully
read?  Or does the motor run all the time?
