Catweasel

The Catweasel is a flexible Floppy Disk Controller for both the Amiga and PC, though we generally refer to the PC version. It enables the PC to read a myriad of disk formats just like the Amiga, but with the added benefit of being able to add different sorts of disk drives out of the box. See the website for more information.

With regards to SPS supporting the Catweasel for dumping or re-writing:

We cannot yet support the Catweasel for technical reasons, primarily because it does not yet enable us to read disks in sufficient detail for dumping, nor does it allow writing IPF files back to disk. And while it does seem that the Mk4 would be suited to the job, current models are still running Mk3 firmware and drivers, meaning that we are still no closer forward in this regard.

As soon as Mk4 firmware is available for these cards, we will do our best to obtain one with a view to support it for these purposes. Until then, our hands are tied.
