Patent number: 7328392Abstract: A disk array system is provided, which can improve data reliability by verifying addressing correctness of data access by applying a redundant code to user data even if using an HDD compatible with serial ATA, etc. whose sector length cannot be extended. When writing the object data to an HDD, a controller stores partly-extracted data of the object data in a control area and performs an XOR operation between the partly-extracted data and a check code generated by calculations. Then, the operation-resultant data (CC-embedded data) are returned to the object data and written in the HDD. Also, when reading the object data from the HDD, the controller fetches the CC-embedded data, performs an XOR operation between the fetched data and the check code, and compares and collates the operation-resultant data with the partly-extracted data in the control area to check the addressing correctness and restore the user data.Type: GrantFiled: November 2, 2004Date of Patent: February 5, 2008Assignee: Hitachi, Ltd.Inventors: Takashi Chikusa, Seiki Morita, Toshio Tachibana, Takehiro Maki, Hirotaka Honma
