¹Logical layout describes imaginary drive parameters which are used to access customer data. Logical layout to physical layout (i.e. actual head, sector) translation is done automatically. Default logical layout variables may be obtained by issuing an "Identify" command.

²Bracketed values show the alternate, jumper selectable, option.
