5.4 Dismounting 
Drives 
 
Since the method and procedure for dismounting the disk drive for replacement of the drive, etc. 
depends on the locker structure of the system, etc., the work procedure must be determined in 
consideration of the requirements specific to the system.  This section describes the general 
procedure and notes on dismounting the drive.  
 
 
 
Damage 
1.  When dismounting the drive which is mounted on the system while power is 
supplied to it. 
• 
The drive to be dismounted must be separated from the loop.  
Dismounting the drive which is not separated from the loop may cause 
an unexpected error.  
• 
If the drive is not separated from the loop, issue an LPB to the drive 
from the initiator in a primitive sequence of the order set. 
• 
It is recommended to stop the spindle motor prior to this loop 
separation operation.  The spindle motor can be stopped by a 
START/STOP command.  It takes about 30 seconds for the spindle 
motor to stop completely. 
• 
Then, dismount the drive using the drive mounting/dismounting 
mechanism, etc. of the system.  If the drive is dismounted while the 
spindle motor is running, special care is required to avoid excessive 
vibration or shock to the drive.  It is recommended to stop the operation 
once the SCA connector breaks off contact and wait until the spindle 
motor stops (about 30 seconds) before dismount the drive. 
• 
When storing or transporting the drive, put it in an antistatic bag.  
(Shown in Section 5.1). 
 
2.  When dismounting the drive which is mounted on the system while power is 
not supplied to it. 
• 
Do not move the drive until the drive stops completely (about 30 
seconds if the spindle motor was stopped by a START/STOP UNIT 
command, and about 30 seconds after powering-off when the power 
was simply turned off). 
• 
Then, dismount the drive using the drive mounting/dismounting 
mechanism, etc. of the system. 
• 
When storing or transporting the drive, put it in an antistatic bag.  
(Shown in Section 5.1).
