Output will be as follows.
Code:
11|101.02693|1|20151202|1026.3204|20151127|N|0001
11|-201.00142|2|20151202|-2141.1783|20151127|3|0005

Thanks,

NAME
fdformat - low-level format a floppy disk SYNOPSIS
fdformat [options] 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 Skip the verification that is normally performed after the formatting. -V, --version Output version information and exit. -h, --help Display help and exit. SEE ALSO
