NAME
disktab - disk description file
SYNOPSIS
#include <<disktab.h>>
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.

ns num Number of sectors per track
nt num Number of tracks per cylinder
nc num Total number of cylinders on the disk
ba num Block size for partition `a' (bytes)
bd num Block size for partition `d' (bytes)
