Abstract
A storage device includes one or more storages and one or more control devices to control writing data to and reading data from one of the storages. Each of the control devices includes a memory, a memory controller, and a processor. The memory controller controls writing data to and reading data from the memory. The processor determines whether the memory and the memory controller have error correcting functions respectively. The processor determines, when at least one of the memory and the memory controller does not have an error correcting function, whether an error is detected in first data expanded in a first memory region of the memory. The first data includes an error detecting code. The processor saves, when no error in the first data has been detected, the first data into a second memory region of the memory. The second memory region is different from the first memory region.
