Alright, I came across a hard drive on ebay on the cheap. I'm relatively new to SCSI so I could use some help with this. When I turn on the computer the thing spins up (booting from a sys 7.5 disk tools floppy) but once the desktop shows up there is no sign of it (doesn't mount, doesn't show "do you want to format this disk" dialouge, doesn't show up in HD SC Setup (patched). I hope its not the disk. Maybe someone could give me a heads up on what the pins on the front do? I know these control which SCSI id the disk has but I don't really get it. This could be part of the problem if it is set up properly. The diagram reads like this:

33 34

. . RSVD

. . RSVD

. . LED+/RSVD

. . TERM PWR

. . TXD/RXD

. . SCSI TERM

. . TRGT INIT

. . UNIT ATTN

. . SCAM

. . DLYD START

. . AUTO START

. . SPNDL SYNC

. RSVD/LCD-

. . SCSI ID3

. . SCSI ID2

. . SCSI ID1

. . SCSI ID0

Corresponding to the diagram, there are plastic jumpers on SCSI ID3, SCSI ID2, and SCSI ID0. The others do not have jumpers.
