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.
Name Type Description
ns num Number of sectors per track
nt num Number of tracks per cylinder
nc num Total number of cylinders on the disk
b0 str Filename of block zero primary bootstrap for device
ba num Block size for partition `a' (bytes)
bd num Block size for partition `d' (bytes)
be num Block size for partition `e' (bytes)
bf num Block size for partition `f' (bytes)
bg num Block size for partition `g' (bytes)
bh num Block size for partition `h' (bytes)
fa num Fragment size for partition `a' (bytes)
fd num Fragment size for partition `d' (bytes)
fe num Fragment size for partition `e' (bytes)
ff num Fragment size for partition `f' (bytes)
fg num Fragment size for partition `g' (bytes)
fh num Fragment size for partition `h' (bytes)
pa num Size of partition `a' in sectors
pb num Size of partition `b' in sectors
pc num Size of partition `c' in sectors
pd num Size of partition `d' in sectors
pe num Size of partition `e' in sectors
pf num Size of partition `f' in sectors
pg num Size of partition `g' in sectors

se num Sector size in bytes (default 512)
sf bool supports bad144-style bad sector forwarding
so bool partition offsets in sectors
ty str Type of disk (e.g. removable, winchester)
Disktab entries may be automatically generated with the diskpart program.
