Doesn't require a catweasel either.

I've no idea who these people are, but I find
it interesting that they
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).
