Format a diskette specified by device name (such as /dev/fd0H1440 for a 3.5-inch, high-density diskette in drive A).
fdformat [-n] device_name
-n disables the verification performed after formatting.
The fdformat command formats a diskette. Use an appropriate device name to identify the diskette drive (see Chapter 12 for naming conventions for diskette drives). After formatting a diskette with fdformat, you can use mkfs to install a Linux file system or tar to store an archive.
