Over time the PS2 has become famous for many things. Most are good, but one, the disc read error, is a pain in the ASS. Many people think cleaning the laser will fix it. Well, YOUR WRONG. If you are going to try and fix it your warranty will be destroyed. First, remove all the screws on the bottom of the PS2. Take the top of the PS2 off. When you get it open you will notice a tray over the disc drive. Remove that. Since your already in there clean the laser. This will decrease the chances of single player lag. You will notice a white gear near the back of the disc drive. Turn it EITHER way four clicks. Reasemble your PS2 and experience the magic.
