I’m trying to read a Iomega Zip 100 disk through old external Iomega Zip 100 drive, which I've connected to my MacBook Pro through the original USB 1.0 cable. It sounds like the drive is reading the disk (there’s no reason except age that either the drive or disk should be broken), but it doesn’t mount.
Is my MacBook Pro capable of reading this at all? What’s the last OS from which I’d have any hope of reading this disk?
Disk Utility
while the drive is plugged in. Sometimes you can "mount" the drive from there.
