If you're using 3.5 floppys, there probably a utility available for your
operating system of choice to copy the entire contents of the floppy out
to a file on the hard disk... On DOS or Windows, look for rawread.exe on
Unix based systems (BSD, Linux, etc.) use "dd if=/dev/fda0
of=badfloppy.dat" (replace with the appropriate name of your floppy disk
device).

Once you have it on hard disk, open it as binary file and spool the bytes
off to your heart's content!

P.S. One place to get rawread.exe for Windows is
http://www.pamarsystems.com/raw.html (not tried their version, though).
The various UNIX clones have versions of this utility available as well.
