I thought /U was "unconditional", meaning
that you cannot later reverse
the formatting and recover the previous data. Without /U, FORMAT would
save a hidden copy of the FAT (or something like that), IIRC, making it
easier to recover from the format. My MS-DOS 5.0 manual says that with
the /U, FORMAT "Destroys all existing data on a disk", whatever that
means.
/U was also the opposite of /F, I believe.
