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.
