The CD-ROM in the Quadra is indeed SCSI, so that doesn't indicate whether or not your IDE bus is bad.
Almost every brand of hard drive you'll find should be jumpered to master, except for Western Digitals, which should have no jumpers at all.

What version of the Mac OS are you booting the Quadra with? I would certainly try another hard drive on the IDE bus along with zapping the PRAM at least 4 times.

It's the original restore CD for that model computer. The CD itself has this printed on it "SSW version 7.5".

I've used old Macs from around that era, but this is really the first time I've had the guts of one laying exposed like this. I knew that the drive I bought would not be 'officially' supported, but I can't get the drive to be recognized to the point where Drive Setup can tell me that!
