Hi, First, if you have another machine to test with, try connecting the Zip drive to that machine to verify that the drive and its installed disk are functional. If that works, try connecting it with a new disk (if you have one), and see if you can format that disk with the Disk Utility application (found in the Utilities folder in your Applications folder. If this works, then the disk should appear on the desktop; at least in a Finder window. If this works, then your problem would seem to be a problem with the disk that you currently have in your Zip drive. Hope this helps, Ken. Hello There i just salvaged a zip 100 from scratch. I had 2 usb units and a paralell unit.

So i transferred the working drive on the paralell to the working circuits on a usb unit and it loads perfectly on a WinXp box. And i can read 2 zip disks formatted for pc. The problem is that i have around 20 mac formatted zips. And they obviously are not recognized by the pc. The USB tab on the system profiler on mac 10.5.5 recognizes the usb zip 100 drive and all its names and codes. BUT it won't mount the disks on the finder.

It says it's a Iomega Zip 100 ATA Device Type: itapi Rev 23.D If I wanted to use the zip to back everything up, it would cost me plenty, money better spent on an external drive and a USB/Firewire card. Jul 09, 2011  Assuming that the Zip drive is OK and the Zip 100 disk isn't damaged, I think you'd be better off using Iomega's IomegaWare 'Tools' utility to erase/initialize a Zip disk.

Aug 31, 2007  As I wrote at the outset, it may not be worth attempting the conversion, especially since you can find used, external Iomega USB Zip 100 drives for very little now. The first generation of USB Zip drives had an external 5-volt power supply, but the newer ones are smaller, bus-powered devices.

Announcement: Upgrade to macOS Mojave With features like Dark Mode, Stacks, and four new built-in apps, macOS Mojave helps you get more out of every click. I have a USB ZIP-250 drive that I haven't used in years, and I have some even older ZIP-100 disks for it. I am running OS X 10.6.8. Out of curiosity, I hooked up the ZIP drive to a powered USB hub, and put in an old ZIP-100 data disk.
