A Reserved Area (RAREA) bit of one indicates that all or part of the translated address falls within a
reserved area of the medium (e.g., speed tolerance gap, alternate logical block, vendor reserved area,
etc.). If the entire translated address falls within a reserved area the target may not return a translated
address. An RAREA bit of zero indicates that no part of the translated address falls within a reserved area
of the medium.

An Alternate Sector (ALTSEC) bit of one indicates that the translated address is physically located in an
alternate sector of the medium. If the drive cannot determine if all or part of the translated address is
located in an alternate sector it shall set this bit to zero. An ALTSEC bit of zero indicates that no part of the
translated address is located in an alternate sector of the medium or that the drive is unable to determine
this information.
[6]
An Alternate Track (ALTTRK) bit of one indicates that part or all of the translated address is located on an
alternate track of the medium or the drive cannot determine if all or part of the translated address is
located on an alternate track. An ALTTRK bit of zero indicates that no part of the translated address is
located on an alternate track of the medium.
