摘要： According to one embodiment, a data storage device includes an encryption module, a write module, and a controller. The encryption module encrypts or decrypts data. The write module writes, on a storage medium, encrypted data of data received from a host, the encrypted data being encrypted by the encrypting module. The controller causes the encryption module to encrypt data received from a host and to transfer the encrypted data to the write module through a buffer memory, during normal encryption process, and to re-encrypt the data recorded on the storage medium, during re-encryption process. During the re-encryption process, the controller causes the encryption module to decrypt the encrypted data read from the storage medium, to store the decrypted data into the buffer memory, and to re-encrypt the decrypted data from the buffer memory by the encryption module and to transfer the re-encrypted data to the write module.

摘要： According to one embodiment, a storage device manages a user data area by dividing the area into a plurality of division data areas. The storage device includes a storage module, an access authority setting module, a lock processor, a command receiver, and an unlock processor. The storage module includes the division data areas. The access authority setting module sets access authority with respect to each division data area for each user. The lock processor disables access to the storage module from a host device that reads data from and writes data to the storage module. The command receiver receives from the host device an unlock command including a basic area storing basic unlock information and an expansion area storing additional unlock information. The unlock processor unlocks each division data area, to which access is restricted for each user, based on the basic unlock information and the additional unlock information.

摘要： A data storage device reads data from and/or writes data to a memory medium. The data storage device includes a storage unit for storing a first identifier, an identifier acquisition unit for acquiring a second identifier recorded on a memory medium which is set to the data storage device, and a controller for comparing the first identifier with the second identifier, and then controlling to access to the memory medium for data reading and/or writing according to a relationship between the first identifier and the second identifier. For example, when the first identifier does not match the second identifier, the controller inhibits access to the memory medium for the reading of data. But, when the first and second identifiers match, the controller permits access to the memory medium for the reading and writing of data. Since the storage device having an identifier which differs from the identifier recorded on the memory medium inhibits access to the memory medium for the reading and writing of data, the secrecy of data recorded on the memory medium is ensured.
