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.
