The method includes the steps of generating a device driver start request by a driver control program when the OS starts; sending a check command on the basis of the device driver start request; loading the specific device driver corresponding to the specific code contained in the response from the drive unit for the check command; and converting a predetermined host command by the specific device driver and sending the corresponding command to the drive unit under the specific device driver when the predetermined host command for the drive unit under the specific device driver is sent from the host device.
