Summary: | A semiconductor recording medium holds an open flag showing presence or absence of consistency between content data stored in a data storage section and file system management information, in a system region not directly accessible from a host device. Upon receipt of a write request or erase request to the data storage section from the host device, the semiconductor recording medium automatically updates the open flag to "ON" (value showing possibility of inconsistency). When actual consistency is verified, the host device requests the recording medium to set the open flag to "OFF" (value showing presence of consistency). When mounting, the host device refers to the open flag with a special command to judge necessity for error check process. |
