Sounds like a fabulous idea, but I'd suggest this be ported to Unix-like operating systems as well (Linux, BSD, etc), if possible.

was ? its still available :)

Unfortunately it can't be used to read GCR formatted disks, since even
direct access to the 765 controller won't help with that.

uh? maybe before making such claims you should actually understand what you
are talking about ....

while fdrawcmd.sys (and the known frontend "omniflop") are quite nice
software, they can NOT do the impossible. that is, they can obviously only
read (and write) what the controllerchip in the pc is capable of. and that
means: standard FM and MFM formats, at their standard bitrates. NO apple2e
disks, NO amiga format, NO commodore 1541 format.
yes it allows, with some heavy trickery and using a second modified drive,
some limited access to these formats - however, no transfer software that
actually uses this method exists. (there exists disk2fdi, which works
similar, but in plain DOS)

(last not least, notice that neither fdrawcmd nor disk2fdi can *write* those
non standard formats, which was what the OP asked for)

The universe is simple; it's the explanation that's complex.

fdutils is there for years, including "superformat" for creating big-sector
and MSS formats.
