Abstract: A storage partitioning method and a terminal, where the storage partitioning method is applied to a terminal including an embedded multimedia card (eMMC). The eMMC includes a controller and a storage medium. The controller has a partition register. The storage medium includes at least two mutually independent system operating partitions. The mutually independent system operating partitions are obtained by the controller by dividing the storage medium of the eMMC according to predetermined setting of the partition register. The method includes enabling only a first system operating partition in the mutually independent system operating partitions when the terminal is in a power-on state, where the first system operating partition has no data exchange with another disabled system operating partition, and accessing data in the first system operating partition. Hence, the one eMMC in the terminal can satisfy different user requirements, and lead to a simple and flexible design with reduced costs.
