DESCRIPTION

       Disktab	is a simple date base which describes disk geometries and disk partition characteristics.  The format is patterned after the term-
       cap(5) terminal data base.  Entries in disktab consist of a number of `:' separated fields.  The first entry for each disk gives the  names
       which are known for the disk, separated by `|' characters.  The last name given should be a long name fully identifying the disk.

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