Hi all, I have been doing some research. For the longest time I have been using a USB WD 500GB external Hard Drive to play movies on my Rear Infotainment System on my 2018 GMC Yukon with no issues. I have over a 100 movies on this drive for my kids. Recently this hard drive died so I purchased a new a USB WD 1TB External Hard Drive and it wont recognize the drive or content I've added. Trouble shooting Time: I tried formatting the drive into the following formats FAT32, EXFAT, and Mac OS Extended and none worked. I found an old USB 16gb in thumb drive Formatted to FAT32, I put a movie on it plugged it in and it worked. Strange how this one worked but the other one didn't. The other difference besides size of the drive was the thumb drive was USB 2.0 and the new 1TB external drive was USB 3.0. Luckily I was able to find another External USB 2.0 Drive in my junk drawer. Specs on this one are USB 2.0 External 128GB SSD format FAT32. Put a movie on it and low and behold it worked. In my opinion one of two things can be happening. 1st the Rear Infotainment USBs only support USB 2.0 drives. The second idea could be power. Maybe the USB ports in the rear don't supply enough power to a USB 3.0 device in order for it to be recognized by the system. The only way to test my second theory would be to use a USB 3.0 Drive with a separate power supply to see if it works. This way it will be getting power from the trucks limited 110 volt instead of the USB connector. Hopefully this helps others out there. I did some digging like the rest of you and couldn't find any useful info so I thought I would share.
