Abstract
PURPOSE:To realize the effective application and to prevent deterioration of the writing performance of a nonvolatile memory, by checking periodically the memory to exchange disks when the alternate data exceeds the prescribed value and releasing an alternate data storing area. CONSTITUTION:A nonvolatile memory 22 is added to a disk cache control adapter 14 in addition to a volatile cache memory 20. The write data is transferred to the memory 22 as well as to the memory 20 in a wiring state of a write-back system. When the write access given to a magnetic disk device 16 is abnormal, the adapter 14 stores the write data to be given to an abnormal sector into a disk alternate area. In case this alternate area is filled with data, the write data is stored in the memory 22. Then the write data of the memory 22 is periodically checked and the disks are exchanged when this checked data exceeds the prescribed value. Thus the write data is copied to a new disk and the write data storing area is released.
