The BenQ rebadges are in the clear plastic bags and have two vents on the back of the drive. The LiteOn's are in pink bubblewrap.
Press open the bottom of the box to see which kind it is before purchase, or ask an associate to kindly open the box to see what kind of plastic its in.
If that doesnt work, buy it, go to your car, open the box, if its not what you want, go in and return it. Lather, rinse repeat until you get the drive you want.
