     NAME
          disktab - disk description file

     SYNOPSIS
          #include <disktab.h>

     DESCRIPTION
          disktab is a simple database that describes disk geometries.
          The format is patterned after the termcap(4) terminal data-
          base.  Entries in disktab consist of a number of colon-
          separated fields.  The first entry for each disk gives the
          names that are known for the disk, separated by | charac-
          ters.  The last name given should be a long name fully iden-
          tifying the disk.

          The following list indicates the normal values stored for
          each disk entry:

          Name    Type  Description
          bl      num   Number of blocks per cylinder
          ns      num   Number of sectors per track
          nt      num   Number of tracks per cylinder
          nc      num   Total number of cylinders on the disk
          rg      num   Rotational gap

          This information is used by the newfs(1M) command.

     BUGS
          This file shouldn't be necessary.  Instead, the information
          should be stored on each disk.
