Has anyone ran across a prog that will scan a blank DVD disc to see if any part of the surface has any errors before writing??? I've tried Nero CD/DVD Speed but it will only scan a written dics. I would like to scan for errors before writing to dics. I bought a 50 pack of TDKs (TTG02) through BestBuy and I did'nt have any problems for the first 15-20, now I'am hitting alot of bad disc.
