Abstract: According to one embodiment, an electronic apparatus includes a plurality of storage modules, a rewrite module, a start module, and a switch module. The storage modules store a plurality of firmware items, respectively. The rewrite module rewrites at least one of the firmware items other than a firmware item being executed with a new firmware item. The start module starts the electronic apparatus with one of the firmware items. The switch module switches, when abnormality is detected in the firmware item for starting the electronic apparatus, the firmware item to another firmware item to start the electronic apparatus.

Abstract: A storage device stores identification information for identifying a pseudo-uncorrectable error sector, which is treated in a pseudo manner as a sector including an uncorrectable error, in the pseudo-uncorrectable error sector. The storage device further performs data processing on the sector by using the identification information stored in the sector. Moreover, the storage device stores log process information indicating whether an error log is registered in the pseudo-uncorrectable error sector in an error process related to the uncorrectable error that is treated to be included in a pseudo manner in the pseudo-uncorrectable error sector. In addition, the storage device performs data processing by using the log process information and the identification information.
