In one embodiment, there is provided an electronic apparatus. The apparatus includes: a storage device including a plurality of blocks that are units of data erasure. Each of the blocks includes a plurality of pages that are units of data reading or writing. Each of the pages includes: a data area storing a data; and a redundant area storing order information indicating an order of the data stored in the data area. The apparatus further includes: a reading module configured to read the data stored in the data area of each of the pages, in order from a last page to a head page, wherein, in reading each of the pages, the reading module is configured to read the order information stored in the redundant area prior to reading the data stored in the data area; a determining module configured to determine whether currently-read order information coincides with already-read order information; and a reading controller configured to control the reading module such that a data is not read from a data area of a page storing the currently-read order information, when the determining module determines that the currently-read order information coincides with the already-read order information.
