How to handle hard drives properly
Be especially careful when handling and installing the hard drives. Proper handling is paramount to the longevity of the drive. The internal mechanism of the hard drive can be seriously damaged if the hard drive is subjected to forces outside its environmental specifications.
 
Caution: When transporting the hard drive, always use an anti-static bag and the shock-absorbing packaging in which the hard drive was delivered to you.
Always handle only one drive at a time.
Always have one hand under the tray to support the weight of the drive when removing or inserting it.
Always hold the hard drive by grasping the long sides that have mounting holes.
Always use an anti-static mat and wrist strap when handling the hard drive.
Never stack hard drives on top of each other.
Never hit the hard drives in any way.
Never touch the components on the circuit board assembly.
Never cover the small hole on top of the hard drive.
Never place the hard drive near equipment that produces strong magnetic fields.
Avoid moving any hard drive that is turned on and operating.
Avoid exposing the hard drive to extreme changes in temperature to minimize the risk of condensation.
If the temperature difference between the storage location and installation location exceeds 50°F/10°C, for temperature acclimation purposes, leave the hard drive in the new location overnight (or at least two hours) before turning it on.
