Entering Drive Parameters (User Defined)
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 size of a sector gets progressively smaller as the track
Precompensation
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.
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 drive may have even
more sectors per track.
Capacity
The formatted capacity of the drive is (Number of heads) x
(Number of cylinders) x (Number of sectors per track) x (512
bytes per sector)
