Thanks for confirming my suspicions with this comment. Was just messing with an internal Zip-750 drive. I tried both SATA to IDE adapters and an internal USB to IDE adapter. I tried with two different drives using Ubuntu 20.04 and jazip.
With both drives there was a brief moment the the zip disk showed up, once. Then never again.
I eventually just purchased a PCIe IDE controller card and that works as expected.
