22.2.5
Information Bytes (Byte 3 through 6)
This field is only valid when VALID bit is one.
- ILI = 0: This field contains the unsigned LBA associated with the sense key. The LBA reported will be within the
LBA range of the command as defined in the CDB.
Note: An LBA other than the command LBA may be reported on the Reassign Block (07h) command.
Note: When the value that need to be stored in the Information field is greater than 0xFFFFFFFF (e.g. an LBA
greater than 2TiB) the VALID bit will always be set to 0. To retrieve such information in such cases, the drive must be
configured to return sense data in descriptor format. See section 18.10.9 "
Mode Page 0A" for details
- ILI = 1: This field contains the difference (residue) of the requested length in bytes. Negative values are
indicated by two's complement notation.
