Translate Address page
The Translate Address page allows the initiator to translate a logical block address into a physical sector
address or a physical sector address to a logical block address. The address to be translated is passed to the
target during the data transfer associated with the Send Diagnostic command and the results are returned to
the initiator during the Data In phase following the Receive Diagnostic Results command. The translated
address is returned in Translate Address page–Receive Diagnostic.
Field definitions (listed alphabetically)

1 The translated address is physically located in an alternate sector of the medium. If the disc drive cannot determine
if all or part of the translated address is located in an alternate sector it sets this bit to zero.

determine this information.
ALTTRK (Alternate Track)
1 All or part of the translated address is located on an alternate track of the medium or the disc drive cannot determine
if all or part of the translated address is located on an alternate track.
