Abstract: A method and a system for protecting data, a storage device, and a storage device controller are provided. In the present method, when a host accesses data in the storage device, whether the host performs a play operation or a copy operation on the data is first determined. If the host performs the play operation on the data, the storage device continues to execute the play operation so as to allow the host to access the data. On the other hand, if the host performs the copy operation on the data, the storage device executes an interference procedure so as to prevent or retard the data from being copied into the host.

Abstract: A data writing method for writing data from a host system into a flash memory chip is provided, and the flash memory chip has a plurality of physical blocks. The method includes receiving a host writing command and write data thereof, and executing the host writing command. The method also includes giving a data program command for writing the write data into one of the physical blocks of the flash memory chip, and giving a command for determining whether data stored in the physical block has any error bit. Accordingly, the method can effectively ensure the correctness of data to be written into the flash memory chip.

Abstract: A storage device, a memory controller, and a data protection method are provided. The method includes when receiving a read command sent by a host, adopting a corresponding output flow rate limit to determine an operation that is executed on read data corresponding to the read command by the host according to location information included in the read command or a type of a transmission interface between the host and the storage device. The method also includes executing an interference procedure by the storage device to prevent the read data from being copied to the host or slow down the speed of copying the read data to the host when identifying that the operation is a copy operation.

Abstract: A block management method for managing blocks of a flash memory storage device is provided. The flash memory storage device includes a flash memory controller. The block management method includes the following steps. At least a part of the blocks is grouped into a first partition and a second partition. Whether an authentication code exists is determined. When the authentication code exists, the blocks belonging to the first partition are provided for a host system to access, so the host system displays the first partition and hides the second partition. An authentication information is received from the host system. Whether the authentication information and the authentication code are identical is authenticated. When the authentication information and the authentication code are identical, the blocks belonging to the second partition are provided for the host system to access, so the host system displays the second partition and hides the first partition.
