Notes:
1
Number of cylinders: For drives with capacities greater an 8.45 GB the IDENTIFY DEVICE information word 01
limits the number of cylinders to 16,383 per the ATA specification.
2
Logical layout: Logical layout is an imaginary drive parameter (that is, the number of heads) which is used to
access the drive from the system interface. The Logical layout to Physical layout (that is, the actual Head and
Sectors) translation is done automatically in the drive. The default setting can be obtained by issuing an IDENTIFY
DEVICE command
