Abstract:
A judging unit determines whether an accumulated rewrite count management table is in a flash memory. If the accumulated rewrite count management table is not in the flash memory, then a generating unit generates an accumulated rewrite count management table in the flash memory, and a recording unit records an accumulated rewrite count in the accumulated rewrite count management table which is generated. A monitoring unit monitors the lifetime of a storage device based on the accumulated rewrite count recorded in the accumulated rewrite count management table and a rewrite count limitative value recorded in the flash memory.
