A security system for an external data storage apparatus and a control method thereof, in which a data storage is driven by reading an identification (ID), which is input through a key input unit for the purpose of security of the external data storage apparatus, and then checking whether or not the read ID is equal to a previously registered ID, thereby preventing data from leaking out and being damaged in advance by another person, and safely protecting the data of a user. The security system comprises a data storage, in which data is stored; a high-speed serial bus, which connects the data storage with a data terminal, which read and write the data stored in the data storage; a key input unit, which converts an ID, which is input by operation of a user, to an electrical signal and outputs the converted signal; a memory, which stores and sets the ID input by the key input unit; and a control circuit, which, when the ID input by the key input unit is applied, compares the input ID with the preset ID stored in the memory, drives the data storage based on the compared result, and re-arranges storage sectors of the data storage to prevent the data from leaking out of the data storage when an unauthorized data terminal provides access. |
