I'm a car guy not a computer guy!! I have a Panasonic Toughbook CF-72 X laptop, 1.8 Ghz, 789 Mhz, 264 RAM. I bought a 40 gig hard drive (it only came w/20). On my old gateway laptop the HD just slides out the front. I don't want to take this thing apart and not be able to get it back together . Can anyone tell me where the HD is and how to get to it
