The act of removing the circuit board and reinstalling it fixed the harddisk! It must have been a loose or dirty connector on the PCB, a loose wire on the connector block, or the motor was stuck in some strange postion where it could not get started (doubtful). Of course, I am now worried about the thing dying again while writing out data or something, I'll have to see. I will back it up daily for a while.

I have had this problem repeatedly with 2 of 7 7300s I have used over the last year and a half (with Miniscribe 20 Meg drives). We try to leave the machines on all the time to avoid this. Failing that, I have found (after the hassle of opening up the machine a couple of times and pushing on the spindle to free it) that I can turn the power on and give the machine a good whack perpendicular to the axis of rotation of the disk...both machines are working well (I've done it twice on 1 and once on the other). The first time I figured out what was wrong and pushed on the spindle, I found that it took more than a light push to free it. I worried that the drive might be ruined, but this has been going on for more than 6 months now with no catastrophes. The other machines seem to have no problems with this sort of thing. Scott S.
