Got a Imation Super Disk many years ago second hand for my iMac Bondi blue.
Browsing the net, I found this:

Included in the box with the SuperDisk Drive is a 120 MB SuperDisk, a translucent USB cable, an AC/DC power converter & cord, and a CD with the applicable USB drivers. There is a PDF manual included on the CD, but you probably won't need to view it as the CD sleeve has eight little pictures that describe how to connect the drive to your iMac.

I wonder whether anyone kept such a CD and would care to upload?

There also seemed to be a data encryption tool for LS-120 disks:

The second advantage is that SuperDisks are capable of data encryption!  In order to accomplish this, you would have to buy specially marked SuperDisk media, and install a small application onto each computer that you wanted to have access to the encrypted data.  While any SuperDisk can be used to store encrypted data, only the specially marked disks came with the necessary software to accomplish it.

I never saw this software, but would like to try if it should still work with Rosetta.
