Also, if the cd really is scratched, there are treatments to restore them at your local Wally World I believe. In a one time pinch, you could use a century old darkroom technique we used for scratched negatives since long before my time, rub a bit of the grease from the side of your nose into the scratch. But I'd almost bet a new drive would read it as it is. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
