Correct the ATA PASS-THROUGH fixed format sense data offsets to conform
to SPC-6 and SAT-5 specifications. Additionally, set the VALID bit to
indicate that the INFORMATION field contains valid information.
INFORMATION
===========
SAT-5 Table 212 — "Fixed format sense data INFORMATION field for the ATA
PASS-THROUGH commands" defines the following format:
+------+------------+
| Byte | Field |
+------+------------+
| 0 | ERROR |
| 1 | STATUS |
| 2 | DEVICE |
| 3 | COUNT(7:0) |
+------+------------+
SPC-6 Table 48 - "Fixed format sense data" specifies that the INFORMATION
field starts at byte 3 in sense buffer resulting in the following offsets
for the ATA PASS-THROUGH commands:
+------------+-------------------------+
| Field | Offset in sense buffer |
+------------+-------------------------+
| ERROR | 3 |
| STATUS | 4 |
| DEVICE | 5 |
| COUNT(7:0) | 6 |
+------------+-------------------------+
COMMAND-SPECIFIC INFORMATION
============================
SAT-5 Table 213 - "Fixed format sense data COMMAND-SPECIFIC INFORMATION
field for ATA PASS-THROUGH" defines the following format:
+------+-------------------+
| Byte | Field |
+------+-------------------+
| 0 | FLAGS | LOG INDEX |
| 1 | LBA (7:0) |
| 2 | LBA (15:8) |
| 3 | LBA (23:16) |
+------+-------------------+
SPC-6 Table 48 - "Fixed format sense data" specifies that
the COMMAND-SPECIFIC-INFORMATION field starts at byte 8
in sense buffer resulting in the following offsets for
the ATA PASS-THROUGH commands:
Offsets of these fields in the fixed sense format are as follows:
+-------------------+-------------------------+
| Field | Offset in sense buffer |
+-------------------+-------------------------+
| FLAGS | LOG INDEX | 8 |
| LBA (7:0) | 9 |
| LBA (15:8) | 10 |
| LBA (23:16) | 11 |
+-------------------+-------------------------+
