Making a ZIP disk read only *OR* a better backup idea?
I have heard, that if you put a bootable ZIP disk with system 7 on it into a zip drive on a machine running OS 8 or later, it will overwrite the driver. Making the disk un-bootable. Therefore, I was wondering if it is possible to make a ZIP read-only, so that I could back up my SE's two main ZIP disks (that have ethernet configured correctly, etc) on OS 8.
In the past I have cloned the disks to other ZIP's, so I do have some what of a backup.. but I would really rather have an image file saved to dropbox or onedrive.

Zip drivers are odd.

Look about halfway down that page under "Auto update quirk"
Therefore, if you want to not have problems with 'old driver' disks, put an old version of the iomega extension in your Mac OS 8 Extensions folder, and be certain you don't have a new version there too! (Also don't use a new version of Zip Tools.)

I can testify to the Zip driver silent update problem. It's very annoying when you're trying to use the same Zip drive on several Macs. As far as I know it's unrelated to System 7 vs 8 though - it's a question of what version of the Zip software you have installed on each Mac.
The Iomega extension is required only if you use specific Iomega features (eg password protection).
To format a Zip cartridge, use a third party formatter such as Lido.
To mount a Zip cartridge, use a utility such as SCSI Probe.

Yeah, it's a myth that if you put your System 6 or earlier Zip disk into a Mac running later OS, it will be messed up. I've done it thousands of times.It's not a myth - I've experienced the zip driver silent overwrite first-hand. The page you linked to offers an interesting work-around. I no longer have my zip drive, so I can't test it, but it makes sense.
I'm trying to sell the story that you can use your Iomega Zip (Bernoulli, Jaz?) drive or your Syquest safely in any Mac. I provided empirical and theoretical evidence that:
1. Iomega's INIT will only change cartridges which have been formatted using Iomega's tools.
2. You only need a vendor INIT if you use vendor features.
Get rid of vendor INITs and install generic tools to manage your external drives.
