Initialize Drive Parameters allows the host to alter the number of sectors per track and the number
of heads per cylinder. This command does not check the validity of counts of sectors and heads. If
an invalid value is set, an error is reported when another command attempts an invalid access. The
Sector Count register specifies the number of logical sectors per logical track, and the Device/Head
register specifies the maximum head number.
