(2) Logical/physical address conversion
This response data reports the execution results of address conversion specified in
the "Logical/Physical Address Conversion" parameter in the SEND
DIAGNOSTIC command in bytes after byte 4. The format and contents of this
response data are shown in Table 4.58.

The value of the "Page Parameter Length" field in this response
data is a variable length within the range of [2 + 8n] in the FC
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 HDD 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."
