description A storage device which includes a plurality of magnetic disk drives has a storage unit that stores, for each of the plurality of magnetic disk drives, information of whether or not the magnetic disk drive is incorporated in a redundant structure, a specifying unit that specifies, among the plurality of magnetic disk drives, a plurality of magnetic disk drives which have a redundant structure on the basis of the information stored in the storage unit, and a control unit that controls, for the plurality of magnetic disk drives specified by the specifying unit, an execution timing of sweep operation in which a head smoothes a lubricant material such that the sweep operation is executed for a single magnetic disk drive at a time.
