Internal hard drive problems. Help me please! I've loved my rock-solid PowerMac 8600--with 512 megs of RAM and two internal Quantum hard drives (2 Gigs and 1 Gig) until recently when the power supply failed and the screen went dark. I purchased a used one on eBay, and have installed it, but I've hit a snag. It starts up ok with my OS 8.5 cd-ROM disk, but refuses to recognize the internal hard drives like it did before--although it does recognize each of them when they're hooked up as external drives. Neither Drive Setup nor SCSI Probe find them either.
The PDF service manual downloaded from Gamba hasn't been much help, but it did mention that the "back" internal drive must be "terminated." None of the attempted wiring options I've used has worked. There are three available sets of 4-wire groups that emerge from the power supply. One set has "R1" and "S1" on its connector ends, a second set shows "T1" and "U1", and the third set, the longest, is unmarked. There is also a 4-wire set with a smaller connecter end that I assumed would be for an optional Zip drive that I don't have. The only devises in the extra drive bays are my Quantums. Can someone please help me make sense of which power supply connectors need to be connected to my 50 pin Quantum drives so that the computer will recognize them? I would be very grateful to any advice/help from you Mac cognosenti who know about these matters. Greenfield Bowie -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
