Our X-box 360 elite's fan did and we had to get a new 360 slim. On the elite, we loaded both disks of Mass Effect 3 onto the hard drive and were able to play the game without it asking for the disks. On the slime we installed both disks, but it keeps asking for either disk 1 or 2. Do the slims not play the games off of the hard drives? If so why bother giving the option to save them to it. If there is a setting we'd like to know so we don't have to keep switching the disks out.
