Hi RWest. From what you have been experiencing and the problems you have found others have been experiencing, I think the easiest thing for you to do is to replace the drive. This is very easy to do, and not very expensive. Look at the drives here click here the price for a bare drive is about £15 plus postage. I find the customer reviews a good guide, and I know they are genuine - I've written a few myself. I have used LG, Pioneer and LiteOn, and not had a problem with any of them.
