fdformat formats a floppy  disk.  The given special should be the
name  of the  special  file that  correspond to  the floppy  disk
drive.

fdformat recognizes the following options:

-aa   Print information  on the standard output device during for-
     mat.  As it formats a cylinder,  it will print a line of the
     form

             hd=0 cyl=25

     on your screen.

-ii _n_u_m_b_e_r
     Use number (0 through  7; default, 6) as the interleave fac-
     tor in formatting.

-oo _n_u_m_b_e_r
     Use number  (default, 0) as the skew  factor for sector num-
     bering.

-vv    Verify  formatting  and verify  data  written  with the  -w
     option.

-ww _f_i_l_e
     Format the  floppy disk  and then copy  file to it  track by
     track.  The raw device should be used.

The command  mkfs builds  a COHERENT  file system on  a formatted
floppy disk.  The command dos builds  a DOS file system on a for-
matted floppy  disk and transfers files to or  from it.  The com-
mand mount mounts a floppy disk containing a file system to allow
access to it  through the COHERENT directory structure.  The com-
mand umount unmounts a floppy disk.

When errors  occur on floppy-disk  devices, the driver  prints on

between tracks, which  may result in a partially formatted floppy
disk.
