Well, I bought some wooden-stick Q-Tips and cut one of the "puffs" off.  I
used that raw piece of wood to stick between the circuit card and the HDA
(head-disk assembly) to spin the flywheel for the platter to the left (with
the PCB on top).

If you look between the PCB and HDA, you should see the edge of a silver disk.
That's the flywheel.  Use some sort of skinny object (the Q-Tip is perfect)
to rotate that thing to the left if the PCB is on top.  It'll break free.  You
can then apply power to the drive (you don't have to have the controller
hooked up) to verify you've freed the thing.

Alternately, you can unscrew the PCB, flip it back (be CAREFUL) and spin the
flywheel clockwise by hand.  Make sure that you rebend the static grounding
strap back so it's in contact with the spindle.

The pliers will work, but use needle nosed ones and put a layer of electrical
tape on each of the jaws so you don't score the spindle.  Another way of doing
it is to get a pencil with an eraser.  Put the pencil (eraser end down) on top
of the spindle (so that the pencil becomes an extension of the spindle) and
twist the pencil.
