Abstract

A method for protecting memory proprietary command is provided. By using the logic block area (LBA) address in the header of the LBA mode, the device end can determine whether the data sector in the LBA mode includes a proprietary command. Also, by using the pre-defined computation function to establish a relation among the values stored in a plurality of characteristic point addresses and a specific point address so that he device end can determine whether a proprietary command is received. As the operating system will not filter out the proprietary command wrapped in this manner, the proprietary command can pass the operating system and be executed by the device end.
