Checking burn quality?

How can I check whether I have a reliable burn…can I assume that if Nero CD/DVD Speed shows no damaged/bad sectors on the surface scan, I have a good burn? What else can I do to verify that the disc will be reliable if I only have an lg burner and don’t plan to buy a lite-on/benq etc just to do disc quality scans?

Transfer tests can show a good quality disc if it has no speed drops it usually shows its good too. But really without another drive you cant really tell.
