Abstract: Embodiments provide a terminal, and the terminal includes a body, a cover body covering the body, a circuit board mounted in the body, a central processing unit welded on the circuit board, a control part mounted on the cover body, and a protection switch welded on the circuit board. A hard disk slot for accommodating a hard disk is disposed in the body. The cover body is detachably mounted on the body, and is configured to seal the hard disk in the hard disk slot. The cover body is opened to drive the control part to open the protection switch. An electrical signal variation is generated due to opening of the protection switch. After detecting the electrical signal variation, the central processing unit instructs the hard disk to perform data protection and powers off the hard disk.
