Forum:Mass effect 1 for xbox360, why doesnt it work

Alright. I'm really hoping someone can help me because I've had this problem for a bit. I don't remember when it started. I know I noticed the problem after starting Mass Effect 3 because I wanted to restart beginning with ME1. When I put in ME1, which I played and beat two or three times before on my system, didn't work.

It comes to the start screen... Then it goes into the menu to ask which device am I saving on... As soon as I pick said device it says the disc is unreadable. I borrowed my friends copy. It didn't work in my XBox360.

I went and got my copy professionally cleaned, thinking it was the scratch's. It still didn't work. I checked all the rest of the games I have. Mass Effect 1 is the only games (I have two copies at this point) it did that to. I gave up on it for a bit.

Thinking I needed a brand new copy. I bought said copy TODAY! No scratch's. Beautiful. And the copy I just bought brand new isn't working either.

It comes to the start screen... Then it goes into the menu to ask which device am I saving on... As soon as I pick said device it says the disc is unreadable.

I did do research into the problem but only came up with results saying it was happening to Mass Effect 2. (that may have changed)

People say its the lazer. People say its the Xbox needing a cleaning. People say its the updates. Or to beat up the Xbox until it works.

So my question is, is there a way to fix this without damaging my xbox or the disc because I would really like to play my ME1 again.
