I've had my M3 for about 2 weeks now. I just bought a 128GB and it was already formatted to FAT32. I plugged it in to the front USB and when I got in this morning it said I had 6 notifications but when I plugged into my computer the USB has no files. Is there a special setup I'm missing? I just unplugged it, I didn't see anything special to eject it like on a computer you have to eject before unplugging the drive. Do I have to set up a file on the USB?
