ABSTRACT:
Conventional methods for appending a validation code are not applicable to a disk array system in which the disk array comprises disk devices having a fixed sector length. The present invention solves this problem by separating validation codes from data blocks, bundling them together in blocks that can be easily matched with sectors, and carrying out all the associated management and control by hardware, such as coordination between validation codes and data blocks and operations of reading from and writing into the disk devices, thereby offering the same level of reliability as with conventional systems.
