Uncharted 2 loading issues

I've been playing UC2 a lot lately, and a few days after I got it the first loading screen with the dagger would get stuck, and the dagger would just keep spinning

I deleted the installed files and update and re installed them, and this fixed that, for a few days

It started happening again a few days ago, and I just deleted the system files and update and re installed them again, yet this time it didn't work and i'm stuck on the dagger loading screen for minutes on end.

Is there any solution to this? I looked it up and did exactly what people recommended. I thought it could be my BR Drive but everything else plays fine in my PS3

Have you tried Cleaning the Disck,have you Scanned your Hard drive for possible faulty sectors ?

Maybe you just ARENT letting it load. How long has it "kept spinning" for?

it kinda takes for a while for the game to do the initial loading since the game doesnt really install itself on the hard disk like other games so every time you start it kinda unpacks some things and all that stuff...it takes a while sometimes even longer then others...u just have to let it spin. if the dagger stops spinning then you do have a problem...or if it spins for more than a minute or so
