Hard Disk Configuration
The hard disk drive parameters are:
Parameter Description
Type The number designation for a drive with certain identification
parameters.
Cylinders The number of cylinders in the disk drive.
Heads The number of heads.
Write Precompensation The size of a sector gets progressively smaller as the track
diameter diminishes. Yet each sector must still hold 512 bytes.
Write precompensation circuitry on the hard disk compensates for
the physical difference in sector size by boosting the write current
for sectors on inner tracks. This parameter is the track number
where write precompensation begins.
Landing Zone This number is the cylinder location where the heads normally park
when the system is shut down.
Sectors The number of sectors per track. Hard drives that use MFM have
17 sectors per track. RLL drives have 26 sectors per track. ARLL
and ESDI drives have 34 sectors per track. IDE and SCSI drives
can have even more sectors per track.
Capacity The formatted capacity of the drive based on the following formula:
(Number of heads) X (Number of cylinders) X (Number of sectors
per track) X (512 bytes/sec)
