Kryofluxing PC Floppies

There is a distinct impression that Kryoflux was designed to deal primarily with Amiga and C64 floppies, and although PC floppy formats present absolutely no difficulty for the Kryoflux hardware as such, using the software for archiving standard PC 5¼″ media is very far from simple. For working with low-density media in HD drives, a special 300 Kbit/s data rate is used by a PC floppy controller designed for 1.2M drives. I have come across one floppy (5¼″ low density, mass duplicated, circa 1990) where DTC reported a single track as unformatted and couldn’t read any data (there was just a bunch of zeros in the resulting image).
