[. . . ] The page length field specifies the length in bytes of the supported page list. The supported page lists contains a list of all diagnostic page codes implemented by the drive in ascending order beginning with page code 00H. The drive supports only pages 00H and 40H.

B 53 3. 4. 17 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 into a logical block address. The address to be translated is passed to the target during the data-out phase. This phase is associated with the Send Diagnostics command and the results are returned to the initiator during the data-in phase following the Receive Diagnostic command. The translated address is returned in the Translate Address Page as shown in the following tables. The translate address page contains a 4-byte page header that specifies the page code and length followed by 2 bytes, which describe the supplied format followed by the translated address. The page length field contains the number of parameters that follow. The Supplied Format field contains the value from the Send Diagnostic command supplied format field. A reserved area (RAREA) bit of 1 indicates that all or part of the translated address falls within a reserved area of the media (such as speed tolerance gap, alternate sector and vendor-reserved area). If the entire translated address falls within a reserved area, the target may not return a translated address. A RAREA bit of zero indicates that no part of the translated address falls within a reserved area of the media.

An alternate sector (ALTSEC) bit of 1 indicates that the translated address is physically located in an alternate sector of the media. If the drive cannot determine whether all or part of the translated address is located in an alternate sector, it will 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. An alternate track (ALTTRK) bit of 1 indicates that part or all 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. The Translated Format field contains the value from the Send Diagnostic command translate format field). The values are 000 (Logical block format) or 101 (Physical sector address format). The Translated Address field contains the address supplied by the initiator in the Send Diagnostic command. [. . . ] The table summarizes the function and the default value of each bit.
