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).
