Byte 2 If the
incorrect length indicator (ILI) bit is zero, the re-
quested block of data from the previous command did not
match the logical block length of the data on the disc. If
the ILI bit is one, the request block of data from the
previous command matched the logical block length of the
data on the disc.
The sense key indicates one of nine general error cate-
gories. These error categories are listed in Appendix B.2.
Bytes 3–6 When the valid bit is 1, the information bytes contain the
logical block address of the current logical block associ-
ated with the sense key. For example, if the sense key is
media error, the information bytes contain the logical
block address of the offending block.
Byte 7 The additional sense length is limited to a maximum of
0E
H
additional bytes. If the allocation length of the com-
mand descriptor block is too small to accommodate all of
the additional sense bytes, the additional sense length is
not adjusted to reflect the truncation.
Bytes 8–11 These bytes contain command specific data.
Bytes 12–13 The additional sense code and additional sense code
qualifier provide additional details about errors. See Ap-
pendix B.3.
Byte 14 The field replaceable unit (FRU) code is used by field
service personnel only.
Bytes 15–22 These bytes are not used.
