Either you have plugged the ribbon cable in backwards, the jumpers on the drive are set incorrectly, or the drive is just bad. It shouldn't do any head movement at all with just power and the SuperCard Pro board plugged into it. If you did plug the ribbon cable in backwards then it likely damaged the SuperCard Pro board. Make sure you pay attention to the pin 1 (red stripe) orientation on both the SuperCard Pro board and the drive. You could try plugging the drive into the last connector on the cable instead of the middle one. That will reposition the SEL line, which is like moving a jumper for the drive selection.
