Why is the abnormal shutdown way bad for the computer?

Physical composition of the hard disk:

Everyone should have seen the hard drive! The hard drive is divided into 3.5-inch and 2.5-inch sizes based on desktop and notebook computers. We use the hard drive to describe the 3.5-inch desktop computer. In the case of the hard disk is actually a lot of round disk disk, mechanical arm, disk reading head and spindle motor composed of the entire interior as shown:

The actual data is written on the disk with magnetic material, and the reading and writing is achieved mainly through the reading Head (head) on the robotic arm. in practice, the spindle motor rotates the disk, and the arm stretches to allow the reading head to read and write on the disk. In addition, because of the limited capacity of a single disk drive, there will be more than two disk drives in the internal disks Oh!

Why the abnormal shutdown mode will be bad for the computer:

Due to the hard disk in the internal mechanical arm of the head and hard disk contact is very small space, if there is jitter or dirt between the head and the hard disk will cause data corruption or physical hard disk total damage ~ Therefore, the correct way to use the computer, should be in the computer power, it should never move the host, and free of jitter to the hard drive, causing the whole hard drive data to be wrong AH! In addition, do not casually unplug the plug is thought to be a smooth shutdown! Because the mechanical arm must return to the position, so use the normal shutdown mode of the operating system, you can have a better hard disk maintenance Ah! Because he's going to put the hard arm back in position!

Tips: Probably because of the environment, the fans inside the computer often get stuck with dust and cause some noise. A lot of friends just hear this sound is apart "hard to shoot a few down the chassis" there is no sound ~ now you know, the consequences of doing so is often your hard drive is easy to break off! Don't do it again next time!
