 insist that PC 1.44MB floppies be read on a "GENUINE Amiga high
 density disk drive".  In looking it appears that they are using their
 own software, "IPF" (Interchangeable Preservation Format), which
 likely is the real reason behind these edicts. 
 Basically, they have their own software that reads the discs and
 produces a raw image. Then you send them the image and they send the IPF
 back.
 The lack of a formal format specification for IPF means I'm not going to
 be implementing support for it in the FD Reader software. It doesn't
 look like there are many (any?) standard, open formats for raw disc
 archiving. DMK is a raw track dump (including sector headers), but
 AFAICT doesn't have any features to represent MFM 'weirdness', e.g.
 missing clocks and speed-shifting (which seems to be a feature of quite
 a few copy protection schemes). 
The FDI format (google "Disk2FDI") is open and complete, and there's a
few emulators supporting it (WinUAE, others that are also non-Amiga).
Doesn't require a catweasel either.
