This command transfers sense data to the INIT. 

This command is executed in any state other than a CDB specification error. 

The sense data of the HDD has a length of 48 bytes.  The HDD generates sense 
data in any of the following cases and holds the sense data for the INIT that has 
issued the relevant command: 

If this command is executed when the HDD is holding the Unit Attention 
condition, at that point, if the HDD is not in the sense data hold state, sense data 
showing the Unit Attention condition are created by this command and are sent to 
the INIT, and the Unit Attention condition is cleared. 

If this command is issued when no valid sense data are being held, the HDD sends 
sense data with a sense key which shows "NO SENSE". 

The "Transfer Byte Length" field in the CDB show the number of bytes of sense 
data that can be received by the INIT. The HDD transfers sense data with a length 
that is specified in the "Transfer Byte Length" field or the HDD's own sense data 
length (48 bytes), whichever is smaller. 

When the value specified in the "Transfer Byte Length" shows 48 bytes or more, 
48 bytes of sense data are transferred and the command terminates with the 
"GOOD" status. 

This command reports the "CHECK CONDITION" status and terminates 
abnormally only in the cases where the conditions shown below are detected. In 
this case, new sense data are generated and the sense data held up to that time are 
lost.
