Fine, fine....let's get to it... Is your PS2 the old model or the new model? As some people said already, the data on the CD can't damage the disc drive. As for your modchip, it is an older model but I don't see how it can be the cause of those weird noises. Some PC games that I've bought also make a whole lot of noise when the spin my my CD-ROM drive, while others don't. I can't give an exact answer why the console wouldn't boot your games...I'd blame the modchip, but I have very little experience with those.
