#include <disktab.h>
/etc/disktab is a simple database which describes disk geometries and disk partition characteristics. It is used by disklabel(1M) to initialize the disk label on the disk. Entries in disktab consist of a number of fields separated by a colon, :. The first entry for each disk gives the names which are known for the disk, separated by pipe | 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.
Sy Name Type Description (ty str Type of disk (e.g. removable, winchester)) (dt str Type of controller (e.g.)SMD , ESDI , floppy) (ns num Number of sectors per track) (nt num Number of tracks per cylinder) (nc num Total number of cylinders on the disk) (sc num Number of sectors per cylinder, nc*nt default) (su num Number of sectors per unit, sc*nc default) (se num Sector size in bytes,) DEV_BSIZE default (sf bool Controller supports bad144-style bad sector forwarding) (rm num Rotation speed, rpm, 3600 default) (sk num Sector skew per track, default 0) (cs num Sector skew per cylinder, default 0) (hs num Headswitch time, usec, default 0) (ts num One-cylinder seek time, usec, default 0) (il num Sector interleave (n:1), 1 default) (d[0-4] num Drive-type-dependent parameters) (bs num Boot block size, default) BBSIZE (sb num Superblock size, default) SBSIZE (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 or 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)) (oa num Offset of partition `a' in sectors) (ob num Offset of partition `b' in sectors) (oc num Offset of partition `c' in sectors) (od num Offset of partition `d' in sectors) (oe num Offset of partition `e' in sectors) (of num Offset of partition `f' in sectors) (og num Offset of partition `g' in sectors) (oh num Offset of partition `h' in sectors) (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) (ph num Size of partition `h' in sectors) (ta str Partition type of partition `a') (tb str Partition type of partition `b') (tc str Partition type of partition `c') (td str Partition type of partition `d') (te str Partition type of partition `e') (tf str Partition type of partition `f') (tg str Partition type of partition `g') (th str Partition type of partition `h') |
