So do I. The CD and DD discs were not as good as one would expect.
Possibly getting a brand new drive might help. You can ask a friend if the discs can be read on another PC. Also, you might consider cleaning the discs with a special thing made for that purpose. Used carefully, you might be able to restore a disc if the surfaces has been soiled or marked.
One kind of cleaner is fro the DVD drive, but there is another kind the will clean and polish the surface of the DVD or CD disc surface with a mild cleanser. You can find such in a local store or buy on line. I think you would try first a local store to make sure lit is what your want.
That is the best I can offer.
