i know most of my drives i had to remove the jumper to put it into single master mode before it would work on my Mac.
i tried master with slave present mode but it would not work.
i think that if you have the jumper in on master that is master with slave present mode and it could be messing up how the Mac reads the drive
have you tried other drives in the machine? If its not even picking it up with anything, i'm thinking there could be a remote possibility that the Mac's IDE controller could be dead. Also, check that the jumpers are set right on the drive, check that its set to Master (MA), not Slave (SL) or Cable Select (CS).
If you can, try hooking it (the drive) up to something else via IDE (rather than USB) just to confirm that it's OK. If it is then maybe try a different IDE cable in the 638 and try again

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.
Big Bird wrote:There's a limit imposed on drive size, but it's exclusively a result of the operating system rather than any inherent hardware limitations of the Macintosh. System 6 and 7 up to 7.5 only support partitions up to 2 GB, but will support a drive larger than 2 GB if partitioned into 2 GB sections. However, Apple's drive partitioning tools only support eight partitions per drive, so you're still looking at only 16 GB accessible.
System 7.5 increased the max size of a partition to 4 GB. System 7.5.2 later increased the maximum size to 2 TB, but only on Macs with built-in PCI slots, which would not include your Quadra.
Mac OS 8.1, which introduced HFS+ formatting, allows addressing up to 2 TB of drive space, however, 68k Macs (including your Quadra) cannot use a drive formatted as HFS+ as a boot drive. If you're interested in that kind of setup (say for a server or something), it's easy enough to partition a large drive with a <2 GB HFS-formatted boot partition, and then format the rest of it as an HFS+ data partition.
Certainly if you want to try it, though, the Mac should work with the 120 GB drive, albeit addressing only 2 GB.
Big Bird wrote:Do you mean that the weird jumperless drive mounts on the Quadra? If so, that means your IDE bus and cables are probably good, which is good news. If not, I'm not sure what sort of drive you're describing, and I'm not sure if it will work in the Mac. But the 120 GB is worth trying to make sure everything works in the machine.
Big Bird wrote:If you're using the original CD, you are probably using the "Internal HD Format" application. That's what I remember the formatting utility released with the initial IDE-based Macintoshes. As I posted on another thread, this utility is incompatible with certain drives (particularly newer ones, but perhaps also non-Apple-ROMed drives, as in your case) because it does not recognize the partitioning information the drives leave the factory with. It seems a strong possibility that you having formatted the drive in a newer machine included the partitioning information on the drive, which the Quadra's drive setup utility is unable to recognize.
Big Bird wrote:Do you have a newer system software CD? I'd try booting the Quadra up with an 8.0 CD and formatting the drive there, using Drive Setup 1.0.3 or higher.
(The Quadra doesn't have a PowerPC upgrade card does it? That will cause problems with older versions of Drive Setup/Internal HD Format.)
