PROBLEM TO BE SOLVED: To provide an electronic apparatus that protects OS images stored in a storage from applications.SOLUTION: A hidden region storing OS images is provided in front of a logical volume storing a file of semiconductor storage 11. A value obtained by reducing an offset from an actual physical address is registered in a file system 104 as a physical address of each file with the size from the front top of the semiconductor storage 11 to the end of the hidden region as the offset. If an application 300 generates a request for access to data of the file and the file system 104 calculates the physical address of the data of the file, a storage driver 101 generates as an access destination address an address obtained by adding the offset to the calculated physical address and accesses the access destination address of the semiconductor storage 11.SELECTED DRAWING: Figure 3 |
