NAME

fd − Amiga floppy disk driver

DESCRIPTION

/dev/dsk/fd∗ and /dev/rdsk/fd∗ are special files which access the Amiga floppy disk drives.  Two formats are currently available with a standard Amiga floppy drive:  "Amiga format" and "IBM format".  The only supported density is "double density", that of the Amiga 880K 3.5" format and the IBM-PC 720K 3.5" format. 

The device names are of the form:

where

n is the drive number (0-3).
f is the format (a for Amiga, i for IBM).
d is the density (d for "double density").

A floppy disk is formatted by writing data (such as zeroes) to its format device. 

Since double density Amiga format is the most common on Amiga computers, the "ad" may be ommited from the fdnad[f] names; i.e., /dev/dsk/fd0 is shorthand for /dev/dsk/fd0ad. 

/dev/cage is a special file which, when opened, causes the opening process to become the floppy demon.
