I found (http://www.softpedia.com/reviews/windows/Nero-CD-DVD-Speed-Review-34166.shtml) this.

"Finally, the Disc Quality test is the best part. The type of test that I recommend is the full scan, although it takes more time. When this is complete, you will get two histrograms showing the errors encountered and obtain a final quality score. To cut a long story short, everything above 95 is very good, 100 is perfect, and everything below 75-80 is not enough...for me. Again, there's a lot of additional reading to be done on this topic, and I can assure you it's a very interesting one.

At last, the ScanDisc tool does the same thing as the previous one, but shows the results the same way as Norton's Disk Doctor or other programs like it. Weak disc areas are marked in yellow, bad sectors are red, while green is the color covering reliable areas."

I'm assuming this is what you're wanting to do.
