Figure 3.23 RECEIVE DIAGNOSTIC RESULTS response data: logical/physical address conversion
Note:
The value of the “Page Parameter Length” field in this response data is a variable length within
the range of [2 + 8n] in the SCSI specifications. For example, If multiple logical data blocks are
located in 1 physical sector, or if 1 logical data block is located in multiple physical sectors, n
address information items are reported as the address conversion results.
In the current IDD specifications, multiple address information items are not reported in this
response data, but the “Page parameter length” always shows X ‘000A.’ However, considering
expanded specifications in the future, the INIT should make it possible to correspond to variable
lengths for the “Page parameter length.”
The “Address Format Before Conversion” field in byte 4 and the “Address Format After
Conversion” field in byte 5 are the same values as the codes which show the expression format for
address information specified by the SEND DIAGNOSTIC command parameters. The “Address
Format After Conversion” field shows the expression format of the address information reported in
bytes 6 to 13 of this response data. “Address format” codes are as shown below.
Code Address Format

1 0 0 Byte Distance from the Index Format
