I think it may be a bad SCSI chip. The hard drive was working perfectly. I only bought it 2 days ago and have had a solid 2 hours use with the HD working. I am not a pro with old Macs and it seems I can't get the hard disk out without removing all of the surround circuitry. I think with all the work involved I might just try buying another one.

I just keep encountering more problems. It now won't boot at all and shows a black screen with the sad Mac icon.
