An actuator is a mechanical device responsible for controlling the machine. It is one that enables the movement of the arm in the hard drive, hence allowing the read/write head to work efficiently. However, it may encounter sudden failure or crash at any time. This may happen when it places the read/write head on variant cylinders, which enables you to access your data. In situations, where an actuator fails, the data stored in the hard drive cannot be accessed. But, the data can be easily accessed and restored, if you have previously created a backup file. However, it would be unfortunate if the backup fails to restore the data. In such situations, you can count on Hard Drive Recovery Services to recover your data completely.

Usually, two kinds of actuators are used in the hard drives, Voice Coils and Stepper Motors.

Voice coils are used in modern or new technology hard drives, which work on the basis of servo system (closed-loop feedback system). However, both types of actuators can fail.

While working on your system, if suddenly, you hear some strange or weird sounds coming out of the hard drive, you may ignore that, if you are busy with your work. But after some time your computer screen starts to flicker and it eventually shuts down. When you try to boot your system again, the CPU lights do turn on but the system does not boot up.

This situation is the indication of actuator failure as you hear some sounds from the hard drive when an actuator is on the verge of failure. Now, the question is, why does an actuator fails?

It fails due to the following reasons:

• Very strong vibrations.

• Power outage.

• Accidental dropping of the hard drive.

• Servo system malfunctioning or faults.

• Overheating or extremely hot temperature.

Failure of the hard drive actuator may render all your hard drive data inaccessible. So, it is advisable to take regular backup of your data. But, if actuator fails and you do not have any backup file, then you should go for professional Hard Drive Recovery Services. These are specialized services carried out under the roof of Clean rooms to ensure the integrity of the hard drive data. Data Recovery Services are effective in all cases of physical damages of the hard drive or its internal parts.
