If I remember correctly (which is not guaranteed), that program requires 2 floppies and a compatible motherboard. As it was explained to me, there are bit that can't be read or written by the OS, but those bits can be captured as they fly by (from the Amiga disk to the junk floppy in the second drive) in the hardware, and from there, reconstituted into an ADF file.
I know, weird. So, I believe the answer was, not writes. Can't be done, sorry.

Then again, those of us who were around at the time remember that the answer to a PC reading Amiga disks was "Can't be done, sorry", until this came out. ;-)
