We usually call it as RAW when a partition used in its native mode, and without having a file system existed. Raw Recovery is the final method to recover data from your drive, no matter what caused the data loss, no matter what file system it is, no matter which kind of problems with disk: deleted, lost, corrupted, damaged, and formatting. It will scan your storage device in low level, and will recover any data that was not physically destroyed or erased. This is the final weapon, Wow!
