1. You could delete / rename any file. Although File Manager showed that the file is gone, but after re-inserting the card she was there again => FAT has not been updated
2. You can not copy a new file on the card. After copying File Manager showed the file, but byte content and MD5 never corresponded to the original file. After re-inserting the card, the copied file was not there => FAT has not been updated.
3. You could not format the card. Although reported the formatting routines that the formatting has been completed successfully, but after re-inserting the card old Ihnalte were still on the map => FAT has not been updated. Was tried on both the PC and on various smartphones / tablets.
Too bad. The card will be returned. The other reviews after it seems that the 64GB version often has such problems.
