Entering Drive Parameters You can also enter the hard disk drive parameters. The drive
parameters are:
Parameter Description
Type The number for a drive with certain identification
parameters.
Cylinders The number of cylinders in the disk drive.
Heads The number of heads.
Write
Precompensation
The actual physical 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 on the disk surface 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. MFM drives have 17
sectors per track. RLL drives have 26 sectors per track.
ESDI drives have 34 sectors per track. SCSI and IDE
drives have even more sectors per track.
Capacity The formatted capacity of the drive is the number of
heads times the number of cylinders times the number of
sectors per track times 512 (bytes per sector).
