## Abstract

Method for controlling mobile hard disk through mobile device is disclosed, in which, control software installed on a computer is used to detect whether APP control software exists in the same IP address segment with the computer, if exists, control software sends a key confirmation signal to APP control software, which accordingly sends back a feedback signal; when the feedback signal is to use an intelligent mobile device as a key of the mobile hard disk, control software generates a key signal and sends it to APP control software and a hidden sector of the mobile hard disk to save it therein. Through the process, the intelligent mobile device installed with APP control software may be used as the key of the mobile hard disk, then while using which, the key is needed instead of a password, thus the unnecessary loss may be prevented from the oblivion of the password.
