I have tested rawrite2.exe using win95 in protected mode and
was able to read and write disk images of /f144,
/s21(1.68MB) and /f172.
        I then tested using NT4 and all failed.
Attempting to write to floppy gave the following error
message: "Writing Error: (R)etry or (C)ancel?".
The original rawrite also failed to write a 1.44MB image to
a high density floppy formatted with NT's native format
command; issuing the error message: "Attempt to DMA across
64K boundary".
Fdimage successfully wrote the same 1.44MB image from NT's
command prompt.
        If there are any other tests required to prove new dostools
under NT4 I am happy to trial them.
