An electronic device includes a sensing unit, a first control unit, and a second control unit. The sensing unit detects a parameter of the electronic device when the electronic device is tilted and sends a detection signal if the detected parameter exceeds the critical parameter. The first control unit and the second control unit receive the detection signal from the sensing unit. If the first control unit receives the detection signal before the second control unit, the first control unit controls the mechanical hard disk to power off and controls a magnetic head on the mechanical hard disk to reset from a working position to an original position. If the second control unit receives the detection signal before the first control unit, the second control unit controls the magnetic head on the mechanical hard disk to reset from the working position to the original position.
