( K G N F
The Information field contains the following device-type or command-specific informa-
tion:
1) The unsigned logical sector address associated with the sense key.
Informa-
tion 2) The difference between the requested length and the actual length in either bytes or
sectors, as determined by the command. This difference is called the residue.
3) A description of each of the drive's supported commands definition for this field is
contained in Table 5-177.
The Additional Sense Length field indicates the number of addition sense bytes that can
Additional
follow. If the Allocation Block Length specified in the Command Descriptor Block is too
Sense
small to transfer all of the additional sense bytes, the Additional Sense Length byte value
Length
is not adjusted to reflect the truncation.
Command-
The Command-Specific Information field is valid only for Sense Data for a failed REAS-
Specific

Informa-
descriptor not reassigned or, if all the defect descriptors were reassigned, FFFFFFFFh.

The Additional Sense Code field indicates further information related to the error or ex-
Additional
ception condition reported in the sense key. If the drive does not have further related
Sense
information, the additional sense key is set to NO ADDITIONAL SENSE INFORMATION.

Key Specific bytes may be 0 when the sense key is NOT READY.
The contents of the Sense-Key Specific field are unique to each sense key. Table 5-177
