Take a look at the big capacitor on the controller.  It's probably
marked C2 on the board.  Do the ends look bulged or otherwise
damaged?  I recently plugged (not once, but twice!) a drive in with
the header shifted one row to the right, and blew this capacitor on
two different controllers.  A trip to my local Radio Shack and a
little soldering cured them.  But the symptom was the same - whirring
disks, no reading.
