It is a 2 drive mk2 player, the drives are 2 30 gb fujitsus pulled out of my 60 gb mk2a and then reformatted. I have never seen the disk not found errors on this player, the cable *seems* to be ok.

IIRC one playlist would play just fine, but reselecting it would cause it to pause. It was a strange error, and I don't think I can recreate it on purpose.
