Original Abstract Submitted

according to one embodiment, a magnetic disk device includes a disk, a storage section, a first determination unit, and a first parity management unit. the first determination unit determines presence or absence of an unexecuted command. the first parity management unit searches the storage section for the first parity area after the first determination unit determines that there is no unexecuted command. the first parity management unit generates the first parity based on the first data in the first data area if the first parity area is detected as the invalid parity area, and writes the first parity to the first parity area.
