My standard ploy when I encounter this problem is to pick up the (Mac
II) box and rapidly jerk the box, rotating it partially in the same
geometric plane as the drive and thus unsticking the drive platters and
heads.
However, there is also the possibility that the lubricant in the drive

Some drives have a rubber or soft plastic bump stop for the head actuator. If
stored for a long period of time with the heads parked, the part of the
actuator that touches the stop can get stuck to it - or the material the stop
is made of can deteriorate and get sticky.

Hi Wesley,
Short answer is no.
Here's the reason why.
There is a rubber bump stop on the inside. The rubber deteriorates over time
and becomes sticky.
Only way to fix it is to open the drive, dismantle the drive magnet which
controls the movement of the arm on which the read/write heads ride.
There are several voodoo fixes that might help. Since the drive is somewhat
inaccessible try turning the whole computer upside down for maybe a half hour
and then try booting in that position. Another fix is to remove and freeze the
drive, overnight in a cold freezer, then try installing it
