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:
