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

The actual physical size of a sector gets

 

Precompensatio

progressively smaller as the track diameter

 

 

n

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).
