I thought dd copied sectors, regardless of the format. You should still
be able to back up the disks and restore to another floppy.
As long as you use the standar number of tracks and sectors, not a
proprietary format that reprograms the timings and the checksums sizes,
payload sizes, etc.
Floppy drives are very dumb, the processor has to switch the motors on an
off "manually" timing the operations. Very different from modern media.
Also means that the processor can not order the operation and forget, but
instead keeps busy.
