Hi all. I have seen some dude using a hard disk attached to the back of the laptop screen. He literally just took out of the hdd of the bag, plugged into USB and attached it to the back of the screen. By the view how hdd sticked to the laptop seems like some kind of a magnet. I am sure it wasn't anything like glue. The laptop was a new macbook pro with a thin screen which kind of made me think that if that hdd had a magnet it might damage the screen ?
