It's about my SD card. I formatted the Micro SD card, slipped it into an adapter, and the Dingoo reads it fine, but when I connect it to the computer while the SD card is in the Dingoo, the computer won't read it right at all. While it shows nothing in the SD card on the computer as well, it also shows absolutely nothing in the Dingoo, when I know there are many files inside. Not to mention, when I try to move stuff to the SD card while it's in the Dingoo from the computer, it will never allow me to do so. Is it the sd adapter? Can only true Mini SD cards work? I don't know and I need help please.
