Notes:
1 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
