Chips Frying Lasers: –
The chips basicly inject data into the stream at the right time so the ps2 thinks it read it from the disc. This also makes the ps2 think it can read the disc, and the "disc read error" thing goes away. That's basicly a timeout, since the process of trying to read the disc tasks the laser and the ic that drives it as hard as possible, there is a time limit on it. But not when you install a chip, so yes, it can fry more than just the laser, IF you dont take care of your games, and IF you aren't bright enough to get that if it isn't reading the disc already, it isn't going to, in less than a minute or so. But if you are more patient than I, and are willing to watch it say "reading disc" for as long as it takes, eventually something will fry.
Laser diodes eventually burn, period.
Recordable media only makes about 30% of the reflected light that that stamped media does, and are that much harder to read.
Using the hard drive has nothing to do with the laser, nor does it count on the laser's life.
A toxic agent on a dangerous mission so secret, even I don't know what it is, because if I did, I would have to kill myself. I don't even know who's side I am on.
