If your PS3 is not reading inserted discs, you can fix it by restoring the system settings(it should work if your Blu-ray drive is functional).

The first option is to blow on the disc or wipe it gently with a tissue. That will generally fix the problem.
Usually stores like Game Crazy and the Radio Shack Repair Center offer to buffer discs, but buffering is for scratches in discs, I'm not sure if it can fix a crack.
No the PS2 does not play PS3 games that are on Blue Ray Discs and can only be played n the PS3
It reads the discs whether they are CD DVD or BluRay, it can not write or burn discs
you can't you will have to buy another one because ps3 discs are always getting scratched if it was a wii disc you could repair it but ps3 discs you can't and ps3 sucks the wii is awsome even the ps2 is better than the ps3
