1-1. Operating Precautions When Replacing Hard Disk Drive
Prolonging Life of Hard Disk Drive
The life of the hard disk drive (HDD) is shortened by vibration, shock,
temperature, humidity and static electricity.
To prolong the life of the hard disk drive, observe the following precautions.
Vibration, Shock
Excessive vibration and shock to the HDD can damage the internal
heads and media.
In some cases, it may take several months for the heads and media to
become damaged after the vibration or shock is applied.
. Take great care not to drop the product or HDD assembly, and to
avoid collision when handling the product and HDD.
. The HDD is at greatest risk of damage when the power is
turned on, and for thirty seconds after the power is
turned off. Never move, transport or tap the product
during these times.
. Be sure to pack the product and the HDD assembly in the
packaging materials specified by the manufacturer or in a
carrying case that protects the HDD from shock and vibration
when transporting the HDD assembly or the product.
Temperature, Humidity
Use of the HDD in an environmental temperature exceeding the product
specification will accelerate wear of the parts and components of the HDD.
A sharp change of environmental temperature and humidity can cause
troubles inside the HDD such as condensation, even if the environ-
mental temperature and humidity are within the product specifica-
tions.
. The HDD starts up automatically when the main power of the
product is turned on. Always operate the HDD under the
specified environmental temperature and humidity once
the main power is turned on.
. When the HDD is moved into a warm indoor room from the cold
outdoors, the HDD assembly should be left for three hours
or more without removal from the packaging materials or
carrying case.
1-2 (E)
Static Electricity
Static electricity can reach up to several kilo volts and instantaneously
damage the HDD board.
. Be sure to touch the metal rack or similar earthed part
before touching the HDD in order to discharge the static
electricity of your body. We recommend wearing an earthed
wrist-band.
