Once the hard disk is
damaged, there will be many troubles which will bring much inconvenience to us.
The data loss may be the most sever problem. However, if we have pay attention
to hard disk maintenance, the lifetime of hard disk will be longer and there
will be less data loss. Here are some common maintenance skills for hard disk.
1.
Keep the computer in a clean environment
The hard disk uses the
spiracle of filter paper with ultra precision to communicate with the out
side world. It can be used in indoor environment with no purification
equipment. But if it is used in a dusty environment, the filter paper will be
absorbed on the surface of PCBA, and inside of spindle motor, or it will block
the breath filter. Therefore, you should keep it from dust.
2.
Form a good habit to correctly turn off your computer.
While the hard disk is
in working, the sudden power loss may cause a violent friction between head and
platter so that to damage hard disk. And it also may cause the head cannot
reset correctly which lead to scratches on hard disk. When shut down your
computer, you should notice that the flashing light of hard disk is still
blinking or not. Only the light stop blinking and the reading is
finished, can you power off your computer.
3.
Prevent it from high temperature, moisture, and electromagnetic
interference.
Hard disk’s life and
working condition have a great relationship with the temperature. A very high
or low temperature will cause clock frequency changes of the crystal
oscillator, and it will lead to failures of hard disk circuit components. The
magnetic media will has a recording error for thermal expansion. But if the
temperature is too low, the moistures in air will be condensed on integrated
circuit components which causes short circuits.
4.
Avoid shocks when you move hard disk.
It would be best
to wait for ten seconds to move hard disk after the hard drive completely
stopped. When boot, the hard disk is rotating at high speed. Even gently
shaking will lead to friction between the discs and read-write head so that
cause a disk damage or head damage. Therefore, in the boot state, you
should not move hard disk or the box. Waiting for ten seconds and the hard disk
has completely stopped, you can move the host or restarting the
power to avoid damage from moment movement.
5.
Regularly defragment the hard disk.
Regularly defragment
the hard disk can improve the speed, accumulated fragments not only
decrease the access efficiency, but also may cause bad track. It will also
affect the life of the hard drive.
6.
Notice the prevention of the virus.
Regularly killing virus
in your hard disk, and you should pay attention to important data protection as
well as a regular backup. It would be better if you don’t run any
unsolicited applications or open unsolicited e-mail attachments.
7.
Hard disk bad tracks.
The bad track is always
has strong diffusibility in destructiveness, even it is only a cluster. So
you’d better not format hard disk to reduce the diffusibility of bad clusters.
8.Do
not use the hard disk compression.
With the compressed
volume file increases, the hard disk read and write data speed will be slow. If
the disk capacity is enough to you, it’s no need to use the hard disk
compression.
The daily maintenance
of the hard disk is actually very important, if data loss occurs, the best is
to find professional people to help you retrieve data from hard drive.
