A memory storage device and a memory controller and an access method thereof are provided. The memory storage device includes a rewritable non-volatile memory chip having a plurality of physical blocks. The access method includes configuring a plurality of logical blocks to be mapped to a part of the physical blocks and dividing the logical blocks into at least a first partition and a second partition, wherein the first partition records an auto-execute file. The access method also includes determining whether a trigger signal is existent and sending a media ready message to a host system if the trigger signal is existent, so as to allow the host system to automatically run the auto-execute file and receive a first password. The access method further includes determining whether to provide the logical blocks in the second partition to the host system according to the first password received from the host system.

Memory storage device and memory controller and access method thereof

A storage device protection system including a protection control unit, a detection unit, an account/password input unit, an ID acquiring unit, and an encryption unit is provided. The detection unit determines whether a storage device and a key storage device are both coupled to a host. The account/password input unit receives an administrator ID and an administrator password. The ID acquiring unit obtains IDs of the storage device and the key storage device. The encryption unit encrypts the administrator ID, the administrator password, and the IDs of the storage device and the key storage device into encryption data. The protection control unit stores the encryption data into the key storage device and sets an access mode of the storage device as a protection status according to the administrator ID and the administrator password. Thereby, the storage device can be effectively unlocked by using the key storage device.

System and method for locking and unlocking storage device

A data protecting method for a rewritable non-volatile memory module having a first storage area and a second storage area and a memory controller and a memory storage device using the same are provided. The method includes providing default configuration information in response to a boot command from a host system, wherein the host system cannot recognize the second storage area according to the default configuration information. The method also includes requesting the host system to re-boot when a user identification code and a user password receiving from the host system pass an authentication procedure, and providing first configuration information to the host system after re-booting the host system. The host system can recognize the second storage area according to the first configuration information. Accordingly, the method can effectively protect data stored in the rewritable non-volatile memory module.
