no problem. I do not succeed with '/dev/fd0' though . . .

X: is an entry for a file system, where you can save files, ls, mkdir,
etc.

\\.\X: is an entry for a raw device. This means, the complete
floppy is treated as one single file. E.g. you can make a tar
archive on a floppy as a file:

        tar cvf foo.tar ....
        cp foo.tar //a          <-- Cygwin path for drive a: as
                                    file system.

or the whole floppy _is_ the tar file:

        tar cvf /dev/fd0 ....

OK? After the last command, it's impossible, to do a 'ls' on the
floppy, because it's now only one single tar archive. This is
meaningful, if you want to copy files between a UNIX system and
Windows, not connected otherwise.

If you want to use a: as file system, you may also mount it, e.g.

        mount [-b] a: /floppy
