Buy a new one then don't scratch it
If the disc has scratches that make it not work, try using a pencil eraser and rub from the center to the edge. It rubs off a small layer that rubs away the scratches. Hope this helps!
Buy a new game disc without scratches
My first guess is that there must be scratches on the disc that make the reading laser inside the Playstation 3 unable to play the game
nope. what you do is when you make an account on minecraft.net, you can then upgrade your account so you can play the real game.
Make sure the Game disc is not scratched
Wet a clean towel with water and a tiny bit of soap, rub in a circular motion. If that does not work, try using a bit of glass cleaner. I have tried both of those and they don't work but u should just take it to game stop or playntrade.
Because its your disc. The PlayStation loads the game and the disc makes noise.
First step is to turn off the PS3 and then try again, maybe putting a game or something it does recognize in before you try it again. Next step is to examine the Game Disc for scratches and other problems or you can do this step while you are trying something the machine does recognize. Also make sure that it is a PS3 game disc and if it is new there are manufacturing defects so you can return defective items.
The PS3 can not save on the game disc because it does not write to Blu-Ray disc. It is a game, DVD, Cd, and Blu-Ray disc player and does not have the ability to make changes to discs of any type.
Make sure that this game is a ps3 game and also check the disk for any scratches.
Most of the time you do need to keep the disc in the drive to play the game. Manufactuers do this to make sure you are not installing the game on multiple computers.
when you acquire the game it should come with 3 discs (for the xbox) when you make it to a certain point in the game it shows a screen asking for you to insert disc two. you press the open tray button on the xbox or on the controller menu. then insert the second disc, then close and wait a few seconds and there will be a loaded sound and the game should begin again.
