@epicvista64874, either an ‘SD ERR’ or ‘NO SD’ message on your camera’s LCD screen means that your camera can't properly communicate with the SD card. If you've already tried multiple recommended SD cards, formatted the cards on your computer and have already gone through the suggested steps here, this may indicate an issue with the camera's SD card slot. If you contact our Support team, they will be able to look into options for you and assist you on the next steps. You may reach them by phone or chat through https://gopro.com/help/ContactUs.
