-.Ar disk
-.Sh DESCRIPTION
-.Nm Bad144
-can be used to inspect the information stored on a disk that is used by
-the disk drivers to implement bad sector forwarding.
-.Pp
-Available options:
-.Pp
-.Bl -tag -width Ds
-.It Fl a
-The argument list consists of new bad sectors to be added to an existing
-list.
-The new sectors are sorted into the list,
-which must have been in order.
-Replacement sectors are moved to accommodate the additions;
-the new replacement sectors are cleared.
-.It Fl c
-Forces an attempt to copy the old sector to the replacement,
-and may be useful when replacing an unreliable sector.
-.It Fl f
-For a RP06, RM03, RM05, Fujitsu Eagle,
-or
-.Tn SMD
-disk on a Massbus, the
-.Fl f
-option may be used to mark the new bad sectors as ``bad''
-by reformatting them as unusable sectors.
-This option is
-.Em required unless
-the sectors have already been marked bad,
-or the system will not be notified that it should use the replacement sector.
-This option may be used while running multiuser; it is no longer necessary
-to perform format operations while running single-user.
-.It Fl s
-The entire disk is scanned for bad blocks.
-.It Fl v
-The entire process is described as it happens in gory detail if
-.Fl v
-(verbose) is given.
-.El
-.Pp
-The format of
-the information is specified by
-.Tn DEC
-standard 144, as follows.
-The bad sector information is located in the first 5 even numbered sectors
-of the last track of the disk pack.  There are five identical copies of
-the information, described by the
-.Ar dkbad
-structure.
-.Pp
-Replacement sectors are allocated starting with the first sector before
-the bad sector information and working backwards towards the beginning
-of the disk.  A maximum of 126 bad sectors are supported.  The position
-of the bad sector in the bad sector table determines the replacement
-sector to which it corresponds.
-The bad sectors must be listed in ascending order.
-.Pp
-The bad sector information and replacement sectors are conventionally
-only accessible through the ``c'' file system partition of the disk.  If
-that partition is used for a file system, the user is responsible for
-making sure that it does not overlap the bad sector information or any
-replacement sectors.
-Thus, one track plus 126 sectors must be reserved to allow use
-of all of the possible bad sector replacements.
-.Pp
-The bad sector structure is as follows:
-.Bd -literal
-struct dkbad {
-	long	bt_csn;		 /* cartridge serial number */
-	u_short	bt_mbz;		 /* unused; should be 0 */
-	u_short	bt_flag;	 /* -1 => alignment cartridge */
-	struct bt_bad {
-	      u_short bt_cyl;    /* bad sector cylinder number */
-	      u_short bt_trksec; /* track and sector number */
-	} bt_bad[126];
-};
-.Ed
-.Pp
-Unused slots in the
-.Ar bt_bad
-array are filled with all bits set, a putatively
-illegal value.
-.Pp
-.Nm Bad144
-is invoked by giving a device name (e.g. hk0, hp1, etc.).
-With no optional arguments
-it reads the first sector of the last track
-of the corresponding disk and prints out the bad sector information.
-It issues a warning if the bad sectors are out of order.
-.Nm Bad144
-may also be invoked with a serial number for the pack and a list
-of bad sectors.
-It will write the supplied information into all copies
-of the bad-sector file, replacing any previous information.
-Note, however, that 
-.Nm bad144
-does not arrange for the specified sectors to be marked bad in this case.
-This procedure should only be used to restore known bad sector information which
-was destroyed.
-.Pp
-It is no longer necessary to reboot to allow the kernel
-to reread the bad-sector table from the drive.
-.Sh SEE ALSO
-.Xr badsect 8
-.Sh BUGS
-It should be possible to format disks on-line under
-.Tn UNIX .
-.Pp
-It should be possible to mark bad sectors on drives of all type.
-.Pp
-On an 11/750,
-the standard bootstrap drivers used to boot the system do
-not understand bad sectors,
-handle
-.Tn ECC
-errors, or the special
-.Tn SSE
-(skip sector) errors of RM80-type disks.
-This means that none of these errors can occur when reading the file
-.Pa /kernel
-to boot.  Sectors 0-15 of the disk drive
-must also not have any of these errors.
-.Pp
-The drivers which write a system core image on disk after a crash do not
-handle errors; thus the crash dump area must be free of errors and bad
-sectors.
-.Sh HISTORY
-The
-.Nm
-command appeared in
-.Bx 4.1 .
