Have you tried spinning it in your hand back and forth on the plane of disk
rotation right after applying power? This method used to work for me, if it
was a "stiction" problem.


Yes, tried that. It causes the drive to "jerk" if it had otherwise stopped
jerking.

I'm thinking it's not "stiction" per se, since there's movement, just not the
RIGHT movement.
