CDCheck is an application checks your CDs (or some other media) and tells you which files are corrupted. It can also do a binary compare with copy on disk (prefered if possible). It is especially useful for testing old CDs or just burned CDs to see if they are OK. If some files are corrupted that means it would be wise to move your data to some other media or copy it on another CD.
