You can plug in most any SCSI disk, but finding the software to partition and format it is another matter. Apple did install special firmware in particular models of disks so they were recognizable by tools like the SCSI formatter included in 7.0.1 (Apple HD SC Setup). In software that old, you're going to need to find either an Apple-blessed drive or get a hold of the hacked SCSI formatter that accepts whatever drive it finds on the bus.

Copy/Install a System folder and boot from the Zip Drive. We used to have multiple zip disks with multiple systems. Even OS 8.1 will fit on a zip disk if you leave out the file translation software. For now, find a second Zip Drive and set one for ID 5 and the second for ID 6. Hopefully you were able to back up files before the hard drive died.
Also, a program from Mount Anything should work for you. The point of the Apple enabled drives was that the computer would recognize them at startup and did not require special software to mount the drive. Iomega provided Iomega Guest as a small file that could be installed on a friend's computer. Once you used Guest to mount the drive, you could select the drive as the boot device and the Mac would boot from the Zip Drive. Having Guest on your Disk Tools floppy would let you get up and going.

Thanks for the info. I have a decent backup of the hard disk.
In my search for a replacement, I've come across lots of disks in the 1 to 36 GB range. The original disk in my computer is 80MB.
Can I use one of these GB range drives in place of the smaller original one?

Yes, you can use a larger drive - the extra space beyond what the OS is capable of seeing will be wasted, but that's not anything to worry about. Don't go nuts, though - aim for a small-ish drive, 1-2GB.

I acquired two 40MB official Apple drives (made by Quantum) of unknown quality. I tried each one but neither was recognized by the computer. That is, Drive Setup says there are no SCSI disks found to initialize.
I've looked for the "Mount Anything" program that was referenced in an earlier reply but I came up dry. Where can I get a copy?

Hmmmm, two "new" drives, both bad? Strikes me as a little odd. Do you hear them spin up? Are they jumpered as a SCSI ID other than 0 or 7?
This may be what Appaloosa mac man was talking about:

Yes, I agree, but Mt. Everything could possibly be one way of confirming that. Gary has probably tried resetting the PRAM already. It may be worth inspecting the condition of the internal battery, too. A problem involving, for example, the SCSI circuits cannot be ruled out.

I too began to suspect "something else" was wrong. So I set up a SCSI Test environment on a more recent Mac. I pligged each drive in and used Intech's Hard Disk Toolkit on them.
HDT successfully mounted all 3 drives with no data loss apparent. So I'm lookinbg elsewhere. I'll replace the PRAM battery next.

Well I replaced the PRAM battery, zapped the PRAM and loaded up Mt. Everything. Nothing brought the SCSI bus back to life.
I can boot off the floppy drive but that's it. Any other suggestions before I declare this a hardware failure?
