摘要： An access control device which writes data to each of predetermined storage block sets in a storage device of which a storage area has been divided into a plurality of storage blocks. The control device includes a management information storage section and an access processing section. The management information storage section stores, for each of said storage blocks, record enable/disable information indicating whether said storage block is a non-defective block in which the data can be recorded or a defective block in which the data cannot be recorded. If the data is written to each of said storage block sets, the access processing section writes the data only to non-defective blocks in said storage block set based on the record enable/disable information stored in said management information storage section.

摘要： Each of (n−1) 2-bit checking units, where n is an integer larger than or equal to 4, receives n-bit redundant encoded data generated from 1-bit input data, and outputs 2-bit check data based on a result of comparison between bits of the encoded data, combinations of the bits differing in each comparison. An all-bit checking unit outputs all-bit check data based on exclusive ORs of all-bit of the encoded data. An error detecting unit detects errors in the encoded data on the basis of the (n−1) sets of 2-bit check data and the all-bit check data, and outputs the input data on the basis of the result of error detection.

摘要： A RAID system includes a RAID controller that sends to a disc apparatus data to be encrypted by a data relay apparatus connected to the RAID controller and the disk apparatus. When receiving a data transfer request packet indicating a first receivable size, the data relay apparatus establishes a second receivable size that is equal to or greater than the first receivable size and that is a multiple of an encryption data size. When the RAID controller receives a data transfer request packet containing the established second receivable size, and in response to the data transfer request packet thus received, the data relay apparatus receives data of the second receivable size sent from the RAID controller. The data relay apparatus also encrypts the received data in units of the encryption data size, and then the encrypted data is sent to the disk apparatus in units of the first receivable size.
