Floppy formatting
 

I'm looking for a command line based program that is able to format & verify a
3.5" floppy @:

720kb double density
1440kb high density
1902kb high density

With superformat i obtain very often a message of invalid seek, other times i
can't verify the disk even if it has NO PROBLEMS ( tried filling it with a file,
umounting it and diff'ing it - even on a 1440kb disk ).

With for example GFLOPPY i don't obtain such strange things, it always format
the floppy without problems but it's graphical and also it can't reach 1902 kb.

Also mformat has the same problems of superformat ( it's the same afaik ).

Thanks in advance.

have you tried fdformat?
