If the drives aren't spinning at all, then try
a game of "Whack-a-Mole" with them. Remove
drive from Mac. Hold by edges firmly with thumb
and fingers of one hand. Two firm whacks with the
edge of your other palm, allowing the hand holding
the drive to rotate at the wrist, will usually
unstick the motor bearings. Plug drive back in and
see if it spins up. This is a good basic physics
demonstration on the principles of inertia. :)
(Inertia tries to hold the platters still while
the rest of the drive rotates around them.)
Old dead hard drives (that will still spin)
also work great for demonstrating the principles
of gyroscopic forces.
P.S. Do not hit the drive so firmly as to knock
it out of your hand. That would be bad. ;-)
