I bought a USB flash drive about a month ago from Best Buy and gave it to a friend so that he could put a video onto it for me. He took the video from a DVD and put it onto my drive using a Mac. None of us realized that the person that needed to have the video owns a PC. When she plugs in the flash drive she gets a message that the drive is not formatted. Obviously formatting the drive will erase the video. How can she open the video on her PC if the drive is not formatted for a PC?
