I used to format a few random sectors on a floppy leaving rest of the floppy unformatted. Then another program was written to read just these sector. This floppy was not readable on any OS as sector 0 was not formatted. But this was done using dos interrupt, may be in linux it could be done. Regards, Mukund Deshmukh Beta Computronics Pvt. Ltd.
