After reading 4 or 5 answers that were amazingly complicated or assumed you had something called DOS :-) I decided to make a suggestion - how about dd? It is what I always use. Just dd from the floppy to a file on the hard disk and a second dd to make the copy works ok or floppy to floppy to floppy if you have two drives. To be more efficient I suggest you specify a blocking factor that is a multiple of the track size. For example, for a 15 sector/track disk, something like: dd if=/dev/rfd096ds15 of=/tmp/caca bs=30b would work fine. -- Phil Hughes, SSC, Inc. P.O.
