Abstract
A disk control apparatus formats each track of a storage disk device in a short time. The disk control apparatus () has a cache memory () which stores a part of data, a management table () which indicates whether a track of the storage disk device () has been initialized to a predetermined track format, and control units () which create the track format referring to the management table () when an input/output request is received from the host (). The factory shipment format flag of this management table is set to '1' when factory formatting is executed, and the table is transferred to the disk. By this method, high-speed factory formatting is possible.
