摘要：
A storage system comprises a storage medium including a plurality of physical storage areas. The storage system controls a host computer to recognize a logical volume having a plurality of virtual storage areas, reads the data from the physical storage area assigned to the virtual storage area of the logical volume, determines whether or not the read data includes only the specific pattern data, and cancels the assignment of the physical storage area to the virtual storage area if the read data includes only the specific pattern data.
