I just bought Uncharted 3 and Killzone 3 from Amazon and my PS3 slim 500GB doesn't even see either disc. I bought Darksiders 2 when it came out and that has been fine. When I put the brand new Uncharted 3 in the PS3 didn't even "see" a disc, so I put some old game in and it worked fine. Then I tried Uncharted 3 a few more times and nothing, The PS3 spins it for a little while then makes a sound like it's ejecting it but doesn't.
Then I opened my new copy of Killzone 3 and the same darn thing. Help me......................arghhhhhhh!
Everything else is working several old games tried and worked.
Darksiders2 worked new 3 weeks ago.
theres nothing "magnetic" about a disc........
the data layer is a foil that is STAMPED with pits and lands.... a magnet is not going to mess that up. unless the actual foil layer has been scratched like many CDRs tend to do.
Printed/burned discs will not be affected by magnetism..... not even a BD disc that has a thick scratch resistant coating.
It likely all possible that both discs came from a bad batch....... you can ask for a replacement
