A data storage device is composed of a non-volatile semiconductor memory and an attribute information storing section. In the attribute information storing section of the data storage device, information representing the number of sectors in a block and the logical address of the sector at the boundary of the block is stored. A host device into which the data storage device is loaded keeps track of the number of clusters constructing one block and the location of the first cluster of the block in the data storage device, and records data in units of a block. |
