My drive isn't reading games that it used to. Even verbatims. I've read a few tuts on adjusting the POT but there all quite obscure when it comes to which screw to turn. Saying things like, 'the screw next to the sticker under something else' I've open the drive up and have found what is supposed to be the POT but it doesn't even look like a screw. I'd appreciate it if someone could point me to a clear tutorial showing exactly which screw to turn.
