Hi,
I have two broken 80 MB Quantum drives (one from an old SE, one from a Color Classic), and both of them exhibit this problem (heads will not move unless manually pushed).

Well, since I had little to lose at this point, I decided to remove the platter. And guess what? There's a little rubber bumper which has gotten all sticky over time, and the heads rest against this stop and get stuck to it.

Unfortunately, I wrecked the heads when I put the platter back, but with care, I don't see why someone couldn't just remove that bumper and at least get a little more use out of the drive.

Anyway, I imagine this has already been mentioned here, but I thought I'd share my experience.

Was this a single platter drive? You cannot do this to a multi-platter drive unless you have a removal tool. Because once the 2 platters slip alignment, the servo tracks are no longer good. and the drive will click to death.
