(2)  INQUIRY command 
The INQUIRY command is executed normally, but the Unit Attention condition is 
not cleared. 
(3)  REQUEST SENSE command 
The HDD executes the REQUEST SENSE command normally, and sends the sense 
data which show the Unit Attention condition which is currently being held to the 
INIT. At this time, the Unit Attention condition with respect to that INIT is cleared. 
(4)  REPORT LUNS command 
The REPORT LUN command is executed normally, but the Unit Attention 
condition is not cleared. 
2.4.3  UNIT ATTENTION condition multiple hold 
If any Unit Attention condition occurs and another Unit Attention condition 
occurs which is caused by other factors before the first Unit Attention condition is 
cleared by the INIT for which that condition is held, those multiple Unit Attention 
conditions are held and the HDD reports multiple unit attention conditions in 
sequence.  
2.5   Sense Data Hold State 
If the status is the Check Condition status when the status is reported, this HDD 
adds that sense data to the response frame and notifies the INIT of it. 
Therefore, the sense data hold state does not occur and the CA status does not 
occur. 
The function which reports sense data automatically is called the Auto Sense 
function. 
This HDD operates with the Auto Sense function activated at all times and this 
function cannot be deactivated.  Also, since this HDD does not support ACA, it 
does not enter the ACA state.
