Using Zip drive as HDD for Macintosh Plus

It should look like this
Unfortunately, that's a parallel port Zip drive. It looks like it has a SCSI port, but it's not really.
OP (@Jon146) posted this question over two years ago! If you read the rest of page 1, they identified they had a Parallel port unit and got the issue resolved.

Oh man, thanks guys! Any idea why the driver isn't loading?
If you format the Zip drive with the oldest Zip Tools the a driver gets written on the disk and the OS extension is not needed for the disk to mount. Then you just copy your OS files to the disk. I've done it all the way up to 8.6.

Oh, OK, my bad.

4.2 is the needed version.

One of the tricky bits to watch out for is if you're booting a Plus from a Zip disk with version 4.2 of the boot driver on it, but then stick that disk into your G3 (or whatever) which has a later version of the driver loaded, it will automatically over-write the 4.2 driver on the disk with whatever driver it is using, rendering the disk unbootable on the Plus until you reinstall the 4.2 driver on the disk. The disks have a driver written in the boot area on the disks which is separate from the extension driver that gets loaded. Iomega apparently assumed you would always want the latest version of the driver on your disks.
Just FYI

oh, that's a nasty wrinkle. Didn't know that.

Yes, one of those things that make it so you can’t just go about putting it in just any drive!
