Okay, after some digging, it looks like you need to verify that the proper driver for the Zip disk/drive has been installed. If you don't have one, go online and Google "ccadams". Yes, I know, that site caters to the Mac SE, but the author has posted lots of useful software tools with regards to troubleshooting. You'll want to click on the link on the front page that says, "Adding hard drives and removables". The last third of that document talks about booting up using a removable disk, along with a link for downloading a driver that will work on Zip disks.
If after getting the driver taken care of and it still won't mount, check to see that the System Folder has been "blessed" properly (open and close the folder on a working System 6/7/8/9 Mac). Another thing would be to force the Mac into booting off of that disk and drive. Before doing anything, make sure you take note of what SCSI ID the external or internal drive is set as. Also verify that the cabling is good and that proper SCSI termination has been checked. Restart your Mac and press the following keys: Apple + Option + Shift + Delete + (SCSI ID # of drive). You might need an additional pair of hands to attempt those keystrokes, unless you've got long enough and limber fingers to attempt it yourself. }
Mac World Mac Secrets, 5th Edition by David Pogue and Joseph Schorr doesn't say much with regards to booting off of a Zip disk. They just mention how to mount a disk without the driver (wait for the "Welcome to Macintosh" and then insert the disk). I'll check the 4th Edition to see if they have anything useful to add.
