PROBLEM TO BE SOLVED: To provide a storage device controller by which a plurality of storage devices are accessed by host equipment to be connected. SOLUTION: In the storage device controller to be connected with a host 1 and on which the plurality of storages (SD) 15, 16 can be mounted, pieces of partition information are read from MBRs(memory buffer registers) of the plurality of SDs 15, 16; it is constituted so that an MBR of a virtual SD is constituted by converting pieces of the partition information into the partition information of the virtual SD by using an offset value, so as to constitute one virtual SD by combining the plurality of SDs 15, 16 and stored on a memory together with the offset value, when the host 1 accesses the virtual SD by specifying a block number; and the block number is converted into block numbers of the plurality of SDs 15, 16, based on the partition information of the virtual SD and the offset value and the plurality of SDs 15, 16 are accessed. |
