On GNU/Linux or with DJGPP programs on DOS/Windows?

Take a look at djtar's source, it can read raw floppy disks.

dd is part of GNU Fileutils, so its DJGPP port is available.  But it 
cannot access block devices, only character devices and regular files.
However, it shouldn't be hard to write a Filesystem Extension module that 
would support sector-level access to a floppy or a similar device via 
BIOS calls.  When linked with such an extension, dd should be able to do 
what it does on GNU/Linux systems.
