Abruptl system shut down: If your system gets shut down abruptly at the time when your MP4 file is in playing mode or at the time when you are transferring a particular MP4 files from one storage device to another then there are chances that your file will get damaged and becomes corrupted severely. System shuts down abnormally only when there is power fluctuation or operating system crashed or when some dangerous external threat attacks your system.
