HELP. Got HDLoader for my sons PS2 and I am trying to get the system to recognize the drive but system just keeps saying that there is no drive. I have tried 3 drives (2 Barracua 7200.7 80gb & 1 Barracuda ATA IV 40gb) with no luck. The unit has no mod chip and (according to the docs) I'm not suppose to need one. Jumpers are correct and all looks good. Is there some step which is not listed (maybe I should insure the drive is blank?).
