CHAPTER 9 MAINTENANCE

9.1General Information

Samsung Spinpoint M9T hard disk drive achieves high reliability through their mechanical design and extensive use of microelectronics. Their design allows fast, easy sub-assembly replacement without adjustments, greatly reducing the amount of downtime required for unscheduled repairs.

9.2 Maintenance Precautions

When servicing a drive, the service technician should observe the following precautions to avoid damage to the drive or personal injury.

(1) Do not attempt to open the sealed compartment of the Spinpoint M9T hard disk drive, as this will void the warranty and contaminate the media.

(2)Do not lift the Spinpoint M9T hard disk drive by the PCB.

(3)Please handle HDD by side surfaces Please see the Fig. 9-1

(4)Avoid static discharge when handling the Spinpoint M9T hard disk drive.

(5)Do not touch cover and the components on the PCB.

Please see the Fig. 9-2

(6)Do not stack the HDDs in column Please see the Fig. 9-3

(7)Avoid harsh shocks or vibration to the drive at all times. Please see the Fig. 9-4

(8)Observe the environmental limits specified for this product, as listed in section 3.6.

(9)If it becomes necessary to move your computer system, turn off the power to automatically park the heads. Parking the heads moves the heads to a safe, non-data landing zone and locks the heads in place. This helps prevent the media and the heads from accidental damage due to vibration, moving or shipping. Do not move the drive for 20 seconds after removing DC power to ensure that the actuator is completely locked.

Back up your data regularly. Seagate assumes no responsibility for loss of data. For information about back- up and restore procedures, consult your DOS manual. There are also a number of utility programs available that you can use to back up your data.
