Bung a -t 140 in there so you don't get a complaint about mode auto-sense
when the format has not yet completed. 140 seconds to format a floppy
may be a bit excessive, but do bear in mind this doesn't verify the format
as it goes along.

A CAM-based program to format removable media (including UFI floppies)
track-by-track wouldn't have that problem, and would be able to verify,
give you progress indications, etc.

I hope the simple camcontrol example above serves to demonstrate the
problem is more or less cracked. I'm happy to live with a simple shell
script wrapper with the above for now, or even just an alias for csh:

 alias ufdformat 'camcontrol cmd \!* -t 140 -c "04 17 00 00 00 00 00 00 00 00 00 00" -o 12 "00 A0 00 08 00 00 0B 40 00 00 02 00"'

Really going to sleep now.
