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.

if all or part of the translated address is located in an alternate sector it sets this bit to zero.

determine this information.
