Making internal FLASH as MSC

I download STM32CubeF4 from this page. There is an example of MSC in \STM32Cube_FW_F4_V1.3.0\Projects\STM324xG_EVAL\Applications\USB_Device\MSC_Standalone\MDK-ARM.
If I build and download this example with USE_USB_FS definition, antivirus will start checking new disk. But Windows Explorer will not show new disk.
If I delete the body of int8_t STORAGE_IsReady(uint8_t lun) from usbd_storage.c and make it return zero, then Windows Explorer will show new disk, but can not oepn it, so it doesn't work as mass storage device.
How make internal FLASH as MSC using this example?
