I've had little to no success with USB drives and getting the Dash Cam to work. I've tried a few that worked for a day and then stopped. I'd format them on PC again and recreate the TeslaCam folder but then they wouldn't even get recognized again. I've also had some other drives that wouldn't ever get recognized from the beginning. These are formatted FAT32 with the TeslaCam folder on it and nothing else. Before I make a service appointment, I was wondering if someone could recommend a good usb stick that is verified to work. I'll test it with that and then go from there. Thanks!
