An apparatus of this invention is directed to a storage control apparatus that improves the access performance of a storage medium and prolongs the life of the storage medium. The storage control apparatus includes a determiner that determines whether to estimate that data at a logical address area in a logical address space used by a host computer to access a storage medium is fragmented and stored in a plurality of physical address areas in a physical address space used in the storage medium, and a data rearrangement unit that reads the fragmented data by designating a logical address area corresponding to the fragmented data which has been estimated to be fragmented and stored in the plurality of physical address areas in the physical address space, and instructs the storage medium to write the read fragmented data in the logical address area while controlling other write operations, so that the fragmented data is written in continuous physical address areas in the storage medium.
