    Then the design is flawed...

    Really ???

    That's what my JazDrive appears as. From Linux, I can do the same with
    /dev/sda and it works just as well, but DOS doesnae recognise it
    unless it's partitioned...

    mke2fs /dev/fd0H1440

    Why bother with DOS ???

    mke2fs /dev/fd0D720

    I regularly do the latter, and have never had any problems with it...

    Again, why bother with DOS ???

    If I do, then RedHat have been supplying a patched version since at
    least RedHat 4.1 when I started with Linux - I've been doing the above
    since then...

    For reference, from this system:
