Question:  5.13. Why Does fdformat Require Superuser Privileges?
Answer:

The system call to format a floppy can only be done as root, regardless of the permissions of /dev/fd0*. If you want any user to be able to format a floppy, try getting the fdformat2 program. This works around the problems by being setuid to root.
