PS2 won't read disk
A lot of time, blue disks have much more problems being read than others. Same with golden disks. Honestly, the best thing you can do, is clean your lense in your ps2 with a Q-tip and a SMALL amount of rubbing alcohal. If its the thin ps2, then all you have to do is open the top and do this. if its the older version of ps2, then you need to open it up, and unscrew the top of the drive to do so, then you will see the lense. I used to have this problem frequently. Andn this is how i solved it. however, its a temperary fix, and you will keep having to do it. honestly, if its already starting to do this, you will probably in the future have more trouble with even silver disks, and black (ps1) disks. If you just bought this ps2, i would suggest gettingg your money back. if you got it for free or something similar... you might just want to either get a new drive (if its an old style one) or buy a new one alltogether if you want to not have to go in and clean the lense every 2 weeks.
