I am dealing with this a *lot* with all these disks from Bob's basement.
The problems seem to be three categories:
1) Disk does not spin up at all. So far it's all been sticking motors,
they don't have a lot of start up torque at all. For the first 4 disks
(ST412, Quantum 30mb, and two ST506) I was able to remove the bottom
board, turn the disks manually (clockwise) while applying power to spin
them up. The motor will start to turn, then as you continue to spin it
with your finger it will go faster as the oils distribute themselves.
Sometimes, the "stuck drive" problem can be overcome by a gentle
"whack" with the handle of a screwdriver or other non-metallic object
to the side of the hard drive, (hopefully) in the direction of spin of
the hard drive. I have done this a few times on 5.25 inch hard drives
at least. With success, Procedure: with the drive powered up, hold it,
and gently give it a whack on the side, in the direction you think it
should spin. If it doesn't work after one or two tries, try something
else.
Caveat: this might affect your drive negatively.
