Remove badsect(8).

Browse Source 
Failure modes of the modern (that is, produced in the last 25 years)
hard drives and SSDs made the utility outdated.  Since the kernel
interface to support it was removed in r324853, cut the userspace
remnants as well.

Discussed with:	bde (who does not like the removal)
Sponsored by:	The FreeBSD Foundation
MFC after:	2 weeks

.Dt BADSECT 8
.Os
.Sh NAME
.Nm badsect
.Nd create files to contain bad sectors
.Sh SYNOPSIS
.Nm
.Ar bbdir sector ...
.Sh DESCRIPTION
The
.Nm
utility makes a file to contain a bad sector.
Normally, bad sectors
are made inaccessible by the standard formatter, which provides
a forwarding table for bad sectors to the driver.
If a driver supports the bad blocking standard it is much preferable to
use that method to isolate bad blocks, since the bad block forwarding
makes the pack appear perfect, and such packs can then be copied with
.Xr dd 1 .
The technique used by this program is also less general than
bad block forwarding, as
.Nm
cannot make amends for
bad blocks in the i-list of file systems or in swap areas.
.Pp
On some disks,
adding a sector which is suddenly bad to the bad sector table
currently requires the running of the standard
.Tn DEC
formatter.
Thus to deal with a newly bad block
or on disks where the drivers
do not support the bad-blocking standard
.Nm
may be used to good effect.
.Pp
The
.Nm
utility is used on a quiet file system in the following way:
First mount the file system, and change to its root directory.
Make a directory
.Li BAD
there.
Run
.Nm
giving as argument the
.Ar BAD
directory followed by
all the bad sectors you wish to add.
(The sector numbers must be relative to the beginning of
the file system, but this is not hard as the system reports
relative sector numbers in its console error messages.)
Then change back to the root directory, unmount the file system
and run
.Xr fsck 8
on the file system.
The bad sectors should show up in two files
or in the bad sector files and the free list.
Have
.Xr fsck 8
remove files containing the offending bad sectors, but
.Em do not
have it remove the
.Pa BAD/ Ns Em nnnnn
files.
This will leave the bad sectors in only the
.Li BAD
files.
.Pp
The
.Nm
utility works by giving the specified sector numbers in a
.Xr mknod 2
system call,
creating an illegal file whose first block address is the block containing
bad sector and whose name is the bad sector number.
When it is discovered by
.Xr fsck 8
it will ask
.Dq Li "HOLD BAD BLOCK \&?" .
A positive response will cause
.Xr fsck 8
to convert the inode to a regular file containing the bad block.
.Sh DIAGNOSTICS
The
.Nm
utility refuses to attach a block that
resides in a critical area or is out of range of the file system.
A warning is issued if the block is already in use.
.Sh SEE ALSO
.Xr fsck 8
.Sh HISTORY
The
.Nm
utility appeared in
.Bx 4.1 .
.Sh BUGS
If more than one sector which comprise a file system fragment are bad,
you should specify only one of them to
.Nm ,
as the blocks in the bad sector files actually cover all the sectors in a
file system fragment.
