In my eariler reply, I had a typo, sorry. The correct syntax for the dd command
is:

dd if=<input file> of=/dev/rfd0.

To check if you have an open file, try fstat -f /floppy (or wherever you have
your floppy mounted).

This may not be the case, since you are able to mount, format, and umount the
device. After you 'cat file > /dev/fd0', what is the exit status? To get the
exit status, you need to type $? after you issue the cat command.
