drive is represented by a data and control file. There are
no partitions.
Messages accepted by the ctl file include:

reset Reset the drive.
format type
Format the floppy. The type sets the density and
type of diskette to be formatted; see format in
prep(8).
A read of the ctl file returns a string describing the form
factor of the diskette, one of 3½DD, 3½HD, 5¼DD, or 5¼HD.
