I have a Panasonic HC-X800 camcorder. I just cannot recover any files after formatting the SD card. I have tried most of the recover software out there but none can find the deleted video files. A few can find the file structure giving the root directory but all the folders are empty. The format of the files that Panasonic use is AVCHD with a file extension .mts. I am beginning to believe Panasonic over-writes the files when formatting, it seems a bit over the top. Has anyone had any success in recovering video files from a Panasonic camcorder? If so, please could you let me know how you did it. Thank you. I have even tried Panasonics own recovery software without success.
