<P>PROBLEM TO BE SOLVED: To provide a storage device which reduces the load of processing for detecting a mistake in writing while maintaining high reliability. <P>SOLUTION: A generation code storage part 122 stores a generation code indicative of an update state of block data associatively with identification information on the block data. A generation code management part 13 stores generation codes in the generation code storage part 122 while allocating a new generation code to detected successive data and new generation codes to respective block data other than the successive data included in write data. A data write part 15 adds the new generation codes to the block data and successive data and writes them to a storage device 19. A determination part 17 determines whether the generation code added to read-out block data or successive data matches the read-out generation code stored in the generation code storage part 122. A data transmission part 18 transmits the read-out block data or successive data when the generation code match each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
