Abstract:
A host device transmits a command from a command transmission unit (101a) along a predetermined command sequence. A storage device (2) receives the command in a command reception unit (202a). An access determination unit (202c) determines the sequence of the command transmitted from the host device (1) and determines that reception of the access to the host device (1) is enabled only when the sequence is identical with a predetermined sequence. Thus, with simple control, it is possible to prevent data destruction by a host device of an old version.
