I believe that if you really want to perform a low level format (replacing all data on the drive with alternating 0's and 1's) you will need to download a utility from the drive manufacture to perform a true low-level format.

If you want to format a partition to create a filesystem then you will want to use `newfs`.

You say that newfs is not recognized on your installation. It may be just that the newfs command is not in the current path. You can check this with `whereis newfs`.

If newfs still doesn't show up then you can run `find / -name "newfs" -print` to find it's location in your system.

As for the usage of newfs, `man newfs` should give you all the gory details.

NAME
fdformat - Low-level formats a floppy disk SYNOPSIS
fdformat [-n] device DESCRIPTION
fdformat does a low level format on a floppy disk. device is usually one of the following (for floppy devices, the major = 2, and the minor is shown for informational purposes only): /dev/fd0d360 (minor = 4) /dev/fd0h1200 (minor = 8) /dev/fd0D360 (minor = 12) /dev/fd0H360 (minor = 12) /dev/fd0D720 (minor = 16) /dev/fd0H720 (minor = 16) /dev/fd0h360 (minor = 20) /dev/fd0h720 (minor = 24) /dev/fd0H1440 (minor = 28) /dev/fd1d360 (minor = 5) /dev/fd1h1200 (minor = 9) /dev/fd1D360 (minor = 13) /dev/fd1H360 (minor = 13) /dev/fd1D720 (minor = 17) /dev/fd1H720 (minor = 17) /dev/fd1h360 (minor = 21) /dev/fd1h720 (minor = 25) /dev/fd1H1440 (minor = 29) The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with fdformat when a non-standard format is being used, or if the for- mat has not been autodetected earlier. In this case, use setfdprm(8) to load the disk parameters. OPTIONS
-n No verify. This option will disable the verification that is performed after the format. SEE ALSO
