The value of the "Page Parameter Length" field in this response
data is a variable length within the range of [2 + 8n] in the ANSI
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
0 0 0
Logical Block Address Format
1 0 0
Byte Distance from the Index Format
1 0 1
Physical Sector Address Format
The description of address information shown in bytes 6 to 13 is the same as the description
specifications in the D List transferred from the INIT by the FORMAT UNIT command. For
details, see the description of the FORMAT UNIT command (Section 4.3.1). Furthermore,
When the logical block format is used, the address is shown in bytes 6 to 9 and zero is
reported in the remaining byte positions. However, when the address information specified in
the "SEND DIAGNOSTIC command points to a position on the disk media which is not used
as physical data blocks, X 'FFFFFFFF 00000000' is reported as the logical block address after
conversion.
