:A floppy disk, also called a diskette, is a disk storage medium composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic carrier lined with fabric that removes dust particles. Floppy disks are read and written by a floppy disk drive (FDD).
  
Altough rarely used nowadays, one still might need/want to use a floppy disk (for example, I practice guitar to backing tracks played from my Yamaha keyboard, which has only a floppy disk drive interface). Common tasks with floppies are described bellow, with available tools to accomplish them.

Reason: please use the first argument of the template to provide a brief explanation. (Discuss in Talk:Floppy disks#)

From Wikipedia:

A floppy disk, also called a diskette, is a disk storage medium composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic carrier lined with fabric that removes dust particles. Floppy disks are read and written by a floppy disk drive (FDD).

Common tasks with floppy disks are described bellow, with available tools to accomplish them.

Installation

Kernel module

Most of the floppy drives should be supported by stock kernel. The module floppy is used as a driver for floppy drives.

The floppy module could not be loaded by default. In such case, it could be loaded with the following command:

$ modprobe floppy

Packages

There are two packages in the Arch package repository related with floppy disks:

Common tasks

Here are the commands needed to perform the most common tasks. In all examples is assumed that /dev/fd0 is linux device for the floppy drive. By default, all these tasks need to be performed as root.

Format

# mkfs.msdos /dev/fd0

Mount

# mount -t vfat /dev/fd0 /media/floppy

Troubleshooting

Unable to get diskette geometry

$ mkfs.msdos /dev/fd0
mkfs.msdos 3.0.5 (27 Jul 2009)
mkfs.msdos: unable to get diskette geometry for '/dev/fd0'

In such case, is probably that the diskette is physically damaged.
