NAME
fdformat
- format floppy disks
SYNOPSIS
[-F fill
]
[-f fmt
]
[-s fmtstr
]
[-nqvy
]
device
DESCRIPTION
The
utility formats a floppy disk at
device
where
device
may either be given as a full path
name of a device node for a floppy disk drive
(e.g.
/dev/fd0 )
or using an abbreviated name that will be looked up
under
/dev
(e.g.
``fd0
''
The options are as follows:
-F fill
Use
fill
as the fill byte for newly formatted sectors.
The
fill
argument
must be a number in the range 0 through 255 using common C
language notation.
The default value is
``0xf6
''
-f fmt
Specify the density settings for a
fmt
kilobyte format, as described in
fdcontrol(8).
-s fmtstr
Specify the density settings using explicit parameters, as
described in
fdcontrol(8).
-n
Do not verify floppy after formatting.
-q
Suppress any normal output from the command, and do not ask the
user for a confirmation whether to format the floppy disk at
device
-v
Do not format, verify only.
-y
Do not ask for confirmation whether to format the floppy disk but
still report formatting status.
For non-autoselecting subdevices, neither
-f fmt
nor
-s fmtstr
may be specified, since the preconfigured media density settings
from the kernel driver will always be used.
However, if
device
is a device with automatic media density selection (see
fdc(4)),
both methods can be used to override the density settings for the
newly formatted medium (without permanently changing the density
settings of
device )
If the
-q
flag has not been specified, the user is asked for a confirmation
of the intended formatting process.
In order to continue, an answer
of
`y'
must be given.
Note that
does only perform low-level formatting.
In order to create
a file system on the medium, see the commands
newfs(8)
for a
UFS
file system, or
newfs_msdos8
for an
MS-DOS
(FAT)
file system.
EXIT STATUS
An exit status of 0 is returned upon successful operation.
Exit status
1 is returned on any errors during floppy formatting, and an exit status
of 2 reflects invalid arguments given to the program (along with an
appropriate information written to diagnostic output).
DIAGNOSTICS
Unless
-q
has been specified, a single letter is printed to standard output
to inform the user about the progress of work.
First, an
`F'
is printed when the track is being formatted, then a
`V'
while it is being verified, and if an error has been detected, it
will finally change to
`E'
Detailed status information (cylinder, head and sector number, and the
exact cause of the error) will be printed for up to 10 errors after the
entire formatting process has completed.
The
utility
has been developed for
BSD 386 0.1
and upgraded to the new
fdc(4)
floppy disk driver.
It later became part of the
Fx 1.1
system.
Starting with
Fx 5.0 ,
it uses the unified density specifications as described in
fdcontrol(8).
