In this case it isn't a 'stiction' problem. The failure is in the
controller, not the hda. I usually leave the computer on 24/7, but
it's kind of hard to replace the motherboard with power on. In this
case, the drive worked perfectly after the motherboard was replaced; i
went belly up when I moved it (power off) from the workbench to the
computer desk.
