STORAGE CONTROL APPARATUS AND CONTROL METHOD

摘要

A storage control apparatus controls a storage device. The storage device includes a first storage area and a second storage area different from the first storage area. An error detection information storage unit generates an ECC for each of data blocks in data to be written, as error detection information. The error detection information storage unit stores generated ECC 1 to ECC 4 in the first storage area. A data storage unit stores data blocks DB1 to DB4 in the second storage area. A detection unit performs error detection on each of the data blocks according to the error detection information read from the first storage area and the data to be written read from the second storage area.
