mformat - add an MSDOS filesystem to a low-level formatted diskette.
mformat [ -t tracks ] [ -h heads ] [ -s sectors ] [ -l volume label ] drive:
Mformat adds a minimal MSDOS filesystem (boot sector, FAT, and root directory) to a diskette that has already been formatted by a Unix low-level format. The follow options are supported: t The number of tracks (not cylinders). h The number of heads (sides). s The number of sectors per track. l An optional volume label. To format a diskette at a density other than the default, you must supply (at least) those command line parameters that are different from the default. Mformat returns 0 on success or 1 on failure.
