All the Xboxes we own contain a Seagate HDD, not a western digital. I dont know why that western digital drive appeared in that 3D xbox thing.
Also, none of the xboxes we own are covered under warranty anymore. We got em just a little bit after they came out, and I dont think I even applied for the warranty.
Btw, not only will it be able to mix music, but also be a kareoki (sorry if mispelled) machine and a photo viewer as well. Viva la Xbox!
