Check and repair floppy disk problems, test an MS-DOS disk, and mark bad blocks in the FAT
Syntax mbadblocks drive:
All unused bad blocks are marked as such in the FAT.
This is intended to be used right after mformat.
It is not intended to salvage bad disks.
Mbadblocks should (but doesn't yet) also try to salvage bad blocks which are in use by reading them repeatedly, and then mark them bad.
