OK, here's the situation... old Performa 638CD, got it for nothing (including the original CDs). The drive that was in it is dead, so I picked up a slightly larger Quantum drive (0.6 GB) for a couple bucks. The Performa boots just fine from the original CD, and reads floppies too... it just won't recognize the hard drive.

Drive Setup 1.3 doesn't see it at all... and neither does SCSIProbe 3.3. I've tried all the possible jumper settings for that drive, and I know the drive is good... it mounts properly (as a standard HFS volume) using my USB drive adapter under OS 9.2.

I was hoping that I could do like this article says, but since the drive won't show up... I can't get past the first step. Is there something simple that I'm missing, or should I just break down and cannibalize the machine for it's working parts?
