9.SH DESCRIPTION
10.I Disktab
11is a simple date base which describes disk geometries and
12disk partition characteristics. The format is patterned
13after the
14.IR termcap (5)
15terminal data base. Entries in
16.I disktab
17consist of a number of `:' separated fields. The
18first entry for each disk gives the names which are
19known for the disk, separated by `|' characters. The
20last name given should be a long name fully identifying
21the disk.
