The REQUEST SENSE command transfers sense data to the host. Sense data
indicates detailed error information on the command whose error was reported
previously. If no error command was reported, SENSE KEY indicates NO
SENSE.
When issuing the REQUEST SENSE command to detect the device status, first
issue the TEST UNIT READY command, then issue REQUEST SENSE.
Allocation Length indicates the length of sense data to be transferred in bytes. If
Allocation Length is 0, the command transfers no data and ends normally.
