Yeah but GTAIV doesn't do this with the 360, it is not GTAIV that has the bugs it is the PS3 silly kids! Check to see if this happens with all of your games. Alot of 360's get the "unreadable disc error." What happens is the magnet that holds the disc down gets stuck in the top of the disc drive. However, it can be fixed in most cases. What you need to do, is find a really strong piece of paper, if you have any one month or 48hour cards that will work great. You can even use the one month that came with gta4 if you want. With a disc in the drive and the drive closed(this wont hurt the disc at all) Stick the card in the top of the disc drive, just wiggle it a little and it will go in, stick it in about 3-4 inches and then swipe it left and right from one side of the drive to the other. Then just eject the disc and then put it back in, it should start right up. This is not a permanent fix, there is no telling how long it will last, you should definitly get it fixed before your warranty runs out, but you should be able to play GTA fine for a few months like this. *Make sure you go to dash before you turn off your xbox or switch games.* For more info search youtube for "unreadable disc fix 100%" I would link the video but youtube isnt working for me....and feel free to email me if you need anything. OR send me a FR and I will respond much quicker because I will probably be playing GTA...my GT is ShowTheWorld
I have had the unreadable disc error for the last 6 months.
