Sense Data
When several items of error information are included in a command's completion

information on that status.
Sense Key
This is a 4-bit code displayed in the sense data. It contains information for
classifying the type of error that was detected.
Status
This is 1 byte of information reported to the initiator by the target device when
execution of each command is completed, which displays the command's
completion state.
