Status Reporting
The drive returns CHECK CONDITION status for a REQUEST SENSE command
only to report errors specific to the command when:
• A non-zero reserved bit is detected in the Command Descriptor Block.
• A drive malfunction prevents return of the sense data.
For Parallel SCSI disk drives, the drive also returns CHECK CONDITION status for
a REQUEST SENSE command to report errors specific to the command when an
unrecovered parity error is detected on the data bus.
Note that any of the previous conditions overwrites the current sense data with the
sense data describing the error encountered by the REQUEST SENSE command
(that is, for the condition stated in the first bulleted entry, the new sense data reflects
that a non-zero reserved bit was detected in the Command Descriptor Block).
The drive returns a maximum of 18 bytes of sense data. The initiator should set the
Allocation Length field in the Command Descriptor Block to 18 to receive all sense
data. If the Allocation Length is set to 0, four bytes of data will be returned (this option
maintains compatibility with SCSI-1 systems).

Sense Data Format for Error Code 70h and Error Code 71h
The sense data format for error code 70h (current error) and error code 71h (deferred
error) is shown in Table 5-168; the data fields are defined in Table 5-169. The
Supported Sense Keys are described in Table 5-170 and the field contents in Table 5-
171. The Supported Additional Sense Codes and Sense Code Qualifiers are described
in Table 5-172 and the Sense-Key Specific Field Contents in Table 5-173.
