ABSTRACT:
A host device1includes an NG table10for storing addresses specifying areas of a bulk memory3into which data cannot be written, a performance-guaranteed environment determination means11for determining whether or not the current environment of the bulk memory3is outside a performance-guaranteed environment where the performance of the bulk memory3is guaranteed, and control means12, 13, 14, and15for writing data in an area of the bulk memory which is specified by an address which is not stored in the NG table10when the performance-guaranteed environment determination means11determines that the current environment is outside the performance-guaranteed environment. Therefore, even if the current environment of the bulk memory is outside the performance-guaranteed environment, the host device can normally write data in the bulk memory, thereby improving the reliability of the system.
