The causes of loss of data are nothing else than the following several common ones: accidentally deleted files/folders; formatted some partition or the entire hard drive (which often happens during the reinstallation of OS); due to wrong operations (unexpected or forcible shutdown, direct or forced pullout, etc.), the invalid partition table error occurred in hard disk, USB flash drive, SD Card and other storage devices, so that they couldn't be identified or just identified as RAW format.
