The 8301 is the video chip. You mean the 8302.
... and I presume you mean mdv1_ spinning?
This could be an 8302 fault (unlikely) or a motherboard problem.
It could also be that the ribbon cable is not fully pushed in.
Mind you if you have the Korean build you likely have socketed cable. If
not then use a long-nosed pliers to work the cable.
Try swapping the drives. If the problem stays with the drive then it is
a faulty drive. If the problem stays the same then it is the 8302
(unlikely) or the motherboard. The drives are started by transistor
switches on the motherboard. I used one of these once to repair a
central heating timer!
