These asterisks are keyed to Figure A–4:
* = See Table A–1
** = See Table A–4
*** = See Table A–5
AV– A Valid bit of 1 indicates the information field contains valid information. A
Valid bit of 0 indicates that the information field does not contain valid data.
ILI– An Incorrect Length Indicator bit of 1 usually indicates that the requested
logical block length did not match the logical block length of the data on the
medium.
Information–
1. The logical block address associated with the sense key.
2. The difference (residue) of the requested length minus the actual length in
either bytes or blocks, as determined by the command, when the ILI bit is set.
Command Specific Information– The logical block address of the first defect
descriptor not reassigned is returned in this field.
SKSV– A Sense Key Specific Valid bit of 1 indicates that the Sense Key Specific
Information is valid. A SKSV bit of 0 indicates that there is no sense key specific
information.
Sense Key Specific Information– If the Sense Key equals 1, 3, or 4, then byte 16
(MSbyte) and byte 17 (LSbyte) indicate Actual Retry Count.
If the Sense Key Specific Information (Byte 2, Bits 0-3) is set to 5-Illegal Request
and the SKSV bit is set to 1, the sense key specific field is defined as Field
Pointers, byte 16 (MSbyte) and byte 17 (LSbyte).
The Field Pointer field indicates which illegal parameters in command descriptor
blocks or data parameters are in error.
A data bit of 1 in byte 6 indicates bad command.
A data bit of 0 indicates bad data.
