I have the same problem with two cards.One has the right capacity the second has 5.7GB both are full of repeating pattern data but no files after scan.Customer claims card from digital camera not from smartphone.Jared":1h784mos said:Open the data of the card up in some hex editor and scroll up and down. Do you actually see data? Do you see any plain text you can read anywhere? Do you see all zeros or all the same repeating pattern?
