    If you use "/sbin/mkdosfs /dev/fd0" it will format the floppy as a dos
    filesystem and check the lowlevel format at the same time. Use of
    "/bin/fdformat" does the lowlevel format only and from the man page it
    does require the use of "/dev/fd0H1440" or equivalent in order to know
    how to do that format.

    However, if that disk has been used for some things (like making a linux
    boot disk) it cannot be reformatted using mkdosfs and would have to be
    reformatted with fdformat first.

    Bottom line - to do the low level format use fdformat, -- to make the
    usable format use mkdosfs.
