A media storage device reads device-specific information from media into memory and performs read/write operations to and from media. In an idle loop after turning on power to a media storage device, a MPU performs processing to update device-specific information while command processing is not being performed, preventing loss of device-specific information due to a sudden cutoff of power. The MPU reads the updated device-specific information from the media while command processing is not being performed, to execute read tests.
