Not a Valid PS2 Disc, I've Tried everything

first off, please don't delete this.
I know you get a lot of these but I feel mine's specific enough to be worth looking at.

This is what I've figured out:
1. Swap magic works, because it loads the original GH2 disk

2. My media type is correct because I made a backup disk of GH2 without changing anything WHILE using cddvdgen and apache to make the disc. This loads fine in Swap Magic
Also I've tried it on 2 different types of media and both copies load fine

3. when I make ANY changes to the main file with GHex, the game won't load and gives the classic "Not a Valid PS2 Disc"

4. This means that I'm doing something wrong with GHex which I can't imagine happening being that I religiously followed the instructions and everything looks right.

5. I tried the entire process on a different computer and it STILL won't work

6. The PS2 is not moded, that may be important to know, not sure

I don't think the media's the issue being that I made a copy that works perfectly. That would also eliminate the burn speed being wrong. There shouldn't be anything wrong with cddvdgen or apache because once again, the backup works fine. All that leaves is the use of GHex being the only thing that's different. But because I religiously followed the instructions time and again, I have no clue what I'm doing wrong.

please please please help me!!!!
I've worked too long at this not to get an answer
Thanks

I never would have guessed it, but the problem was that the lens needed cleaning.....wtf?!
Now all my old discs work fine.

Thanks for your help

Glad you got it working.

I updated this thread based on your solution. I think some people have been overlooking this answer.

no, a PS2 cannot play burnt ps2 games. You need a modded one or swap magic
