-NO SENSE-No specific sense key information to be reported for the designated logical unit. The command was successful. NOTE: This is the normal ending sense code.
 

Code 1

-RECOVERED ERROR-The last command completed ucessfully with some recovery action performed by the target.
 

Code 2

-NOT READY-The logical unit addressed canot be accessed and operator intervention may be required.

Code C

-EQUAL-Indicated a SEARCH DATA command has satisfied an equal comparison.
 

Code D

-VOLUME OVERFLOW-The buffered peripheral data has reached the end of the end-of-partition and data may remain in the buffer that has not been written to the medium.
