I got this disc and put about 60GB of old games and such on it. I decided to open the suitcase and take a look. At first glance I thought there was just an unnamed hard drive inside, but it was actually a Western Digital 500GB Scorpio drive, very cleverly cut out and pasted over it. It looks like the disc has been wet before, but I haven't had any problems so far. I'm not sure why they would sell a 500GB drive as a 320GB drive, but at least it's a decent drive inside.
