Disk control apparatus, disk control method, remote disk control apparatus, and remote disk control method

摘要

A disk control apparatus formats each track of a storage disk device in a short time. The disk control apparatus ( 1 ) has a cache memory ( 14 ) which stores a part of data, a management table ( 20 ) which indicates whether a track of the storage disk device ( 2 ) has been initialized to a predetermined track format, and control units ( 10, 12 ) which create the track format referring to the management table ( 20 ) when an input/output request is received from the host ( 3 ). 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.
