    摘要: According to one embodiment, there is provided a magnetic disk device including a magnetic disk, a storage unit, and a control unit. The magnetic disk includes a recording region. The storage unit is configured to store a value according to number of accesses to each of a plurality of regions obtained by dividing of the recording region of the magnetic disk in association with each of the plurality of regions. The control unit is configured to count a value according to the number of accesses to each of a plurality of regions in a count step unit that is a value determined according to an elapsed time from occurrence of a specific situation and is a value counted per unit access, and to update the value stored in the storage unit.

    摘要: According to one embodiment, a drive array apparatus includes a plurality of data storage drives constituting a drive array and a controller. The controller divides all data storage areas of each of the data storage drives into a plurality of logical unit areas and associates and manages each of the logical unit areas and each of the data storage drives. The controller identifies a logical unit area of an error occurrence object based on a notification from a data storage drive where an error occurred, restores data of the identified logical unit area, and performs reconfiguration processing of the drive array.
