RE: /dev/fd0H1773 ?

Looks like the list is catching up a little...

On my machine, mknod has a different syntax ('mknod /dev/fd0u1722 b 2 60', 
IIRC) and the referenced text file describes the magic device numbers.  So 
I make the device and I've been testing it like this:

% mkfs /dev/fd0u1722
% mount /dev/fd0u1722 /mnt/floppy
% cat /dev/urandom > /mnt/floppy/delme
% umount /mnt/floppy

% mkfs /dev/fd0
% mount /dev/fd0 /mnt/floppy
% cat /dev/urandom > /mnt/floppy/delme
% umount /mnt/floppy

And the first set produces a whole lot of I/O errors while the second set 
works flawlessly.  So I guess it's not working on my machine.  If it would 
help to post the errors, I can dig them up....   I don't know if it's the 
media (which I consider poor quality) or, as I've seen posted, the 1.7MB 
floppy is inherently unreliable...  I'd think media (or BOTH) but I can 
iterate the above and the same media works great as a 1.44 and then fails 
as 1.7 then great as 1.44 ...

Oh yeah, unless I'm doing something stupid....  I don't use floppies on 
Linux at all and mkfs is amazingly fast compared to DOS FORMAT...  SO maybe 
I'm skipping a step that would make the media reliable?  Or maybe I need to 
futz with something like "setfdprm'?  (But I don't really understand what 
the geometry of the disk is).
