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 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.
22.2.6 Additional Sense Length (Byte 7)
Indicates the remaining number of bytes in the sense data. (It is always set to 18h.)
22.2.7 Command Specific Information (Byte 8 through 11)
This field is unused and will be set to zero.
22.2.8 Additional Sense Code/Qualifier (Byte 12 and 13)
The following table shows the description of the combination of Sense Key / Sense Code / Qualifier.
