Something on the order of:

dd if=/dev/fd0 of=/tmp/diskette bs=76800

then swap diskettes, and

dd if=/tmp/diskette of=/dev/fd0 bs=76800


The "format" command will format an unformatted diskette, if you need
to do that.  It is important to use the bs=76800, as a large blocksize
which is a multiple of 7680 makes everything work lots better, as
there are no missed rotations and so forth.
