5.5 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 spindle motor can be stopped by a START/STOP command. It
takes about 15 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. Just in case, stop dismounting once
when SAS connector breaks off contact and wait unitil the spindle
motor stops (about 15 seconds.).
• When storing or transporting the drive, put it in the antistatic bag
(refer to Section 5.1).
2. When dismounting the drive which is mounted on the system while power is
not supplied to it.
• Dismount the drive using the drive mounting/dismounting mechanism,
