ABSTRACT:
A controlling apparatus for controlling a disk array unit includes a cache memory for caching data of the disk array unit; a nonvolatile memory for storing the data in the cache memory; and a control unit for detecting a defective location in the nonvolatile memory where the data is stored defectively and updating information indicating the defection location, for generating an error detection code of the updated information, for writing the generated information and the associated error detection code into an area of the nonvolatile memory different from any area where any information indicating any defective location previously detected and stored into the nonvolatile memory, and for controlling writing the data in the cache memory into a location of the nonvolatile memory designated by any selected one of the information stored in the nonvolatile memory.
