by entering the characteristics of the drive in the fields described below
：

Capacity – displays the capacity of the HDD in megabytes (MB).

Cylinder – indicates the number of cylinders that the HDD has. A cylinder is the sum total
of all tracks that are in the same location on every disk surface.

Head – displays the number of heads in the HDD. A head is a device that reads and writes
data on the hard disk.

Precomp – displays the track where precompensation is initiated. Precompensation is a
feature whereby the HDD uses a stronger magnetic field to write data in sectors that are
closer to the center of the disk. In CAV recording, in which the disk spins at a constant speed,
the sectors closest to the spindle are packed tighter than the outer sectors.

Landing Zone – displays the location of the safe non-data area on a hard disk that is used
for parking the read/write head.

Sector – displays the number of sectors available on the HDD. A sector is the smallest unit
of storage space on a disk.
