SCSI Description
5-124 Maxtor Atlas 10K III
The Translate Address Page allows the initiator to translate a logical sector address,
physical address, or physical bytes for an index address into any one of the other
formats. The address to be translated is passed to the drive with the SEND
DIAGNOSTIC command, and the results are returned to the initiator by the
RECEIVE DIAGNOSTIC RESULTS command.
Table 5-159 shows the format of the Translate Address Page that is returned in
response to a RECEIVE DIAGNOSTIC RESULTS command, and Table 5-160
contains a description of the data fields. Multiple translated addresses are returned if
the logical sector size is greater than 512 bytes (more than one physical data sector).
Translate Address Page-Data Format
Bytes 6 through 13: One set of these bytes is required for each
sector per Logical Block Address.
