[CLUE-Tech] RFI Duplicating floppies

[grant]

I have a good "mostly" answer.  It is a two step process.  This will,
however, copy any type of floppies, DOS, Mac, Linux, whatever, and the
filesystem does not have to be supported by the kernel.  Depending on your
settings, you may have to be logged in as root.

dd if=/dev/fd0 of=/tmp/floppy.img

******Switch diskettes******

dd if=/tmp/floppy.img of=/dev/fd0
rm /tmp/floppy.img


Hope that helps.

Do you have at least 1.44 megs of spare hard drive space? If so, then you can
avoid lots of disk swapping with the following:
(insert source floppy)
dd if=/dev/fd0 of=diskimage
(insert destination floppy)
dd if=diskimage of=/dev/fd0

Does that help, or do you really need to swap floppies back and forth?
