Abstract
An information processing apparatus that controls access to a non-volatile storage medium mounted therein to thereby make it possible to prevent occurrence of a read/write error and physical damage to the non-volatile storage medium. The information processing apparatus includes an HDD as the non-volatile storage medium and a RAM disk on a RAM as the volatile storage medium. An API hook hooks a system call that uses a file descriptor. A frequency of access to a file in the HDD is detected by using the API hook. When the access frequency of a file has exceeded a predetermined value, the access destination of the file is changed from the HDD to the RAM disk, by using the API hook.
