DISKTAB(5) DISKTAB(5) 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 termβ cap(5) terminal data base. Entries in disktab consist of a number of β:β separated fields. The first entry for each disk gives the names which are known for the disk, separated by β|β 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 ba num Block size for partition βaβ (bytes) bd num Block size for partition βdβ (bytes) be num Block size for partition βeβ (bytes) bf num Block size for partition βfβ (bytes) bg num Block size for partition βgβ (bytes) bh num Block size for partition βhβ (bytes) fa num Fragment size for partition βaβ (bytes) fd num Fragment size for partition βdβ (bytes) fe num Fragment size for partition βeβ (bytes) ff num Fragment size for partition βfβ (bytes) fg num Fragment size for partition βgβ (bytes) fh num Fragment size for partition βhβ (bytes) pa num Size of partition βaβ in sectors pb num Size of partition βbβ in sectors pc num Size of partition βcβ in sectors pd num Size of partition βdβ in sectors pe num Size of partition βeβ in sectors pf num Size of partition βfβ in sectors pg num Size of partition βgβ in sectors ph num Size of partition βhβ in sectors se num Sector size in bytes 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 proβ gram.
