On to the man page for fdformat, and I think you did a typo between "fd0H" and "1440" , no space required. So ran it again, and it started formatting the disc, but then crapped out with the output below. Doh, Doh, and thrice Doh. [[email protected] djmons]# fdformat /dev/fd0H1440;mformat a: Double-sided, 80 tracks, 18 sec/track. Total capacity 1440 kB. Formatting ... done Verifying ... Read: : Input/output error Problem reading cylinder 0, expected 18432, read -1 plain_io: Input/output error mformat: Error reading from '/dev/fd0', wrong parameters? Any suggestions, apart from throwing the floppies in the trash? Nigel.
