I have a nice ICL PERQ 2 T2 that I am going to start working with now.

First thing was to try to image the hard drive. It is a Micropolis 1303. It
spins up but when it reaches what I think the correct speed it immediately
spins down. Usually I think there would be a click and then the heads would
recalibrate. But there is no click and no head movement.

I really would like to make an image of the drive.  What are your thoughts?
Are the heads sticking?
Some kind of solenoid that is not releasing the heads? Not properly up to
speed? (but it sounds like the speed is right)
