ABSTRACT:
In an array disk storage system, when a fault occurs in one of a plurality of regular disk storages and a disk storage for parity, restored data generated from data stored in the remaining functioning disks is written to the spare disk storage, and the restored data is copied to a new disk storage which has replaced the faulty disk. The writing of new data is carried out such that new data is written to both the spare disk storage and the new disk storage to which a writing of the restored data from the spare disk storage is being carried out, in response to an instruction from an upper grade device to write the new data.
