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 Out phase 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 the Translate Address page—Receive Diagnostic (Table 142).
