CDCheck, detection & recovery of damaged files

It's a program focused primarily on the identification of errors on a CD (or DVD), but also allows you to do some data recovery.
The main feature of CDCheck is to make a comparison between the data and the data written to hard disk, even if the audio CD (in this case by referring to the tracks WAV Hard Disk): in this case will be able to whether the burning took place in an absolutely identical to the data on your hard drive. It can also check him a CD/DVD to see if there are errors in it (functionality still less powerful than the aforementioned comparison).
The part on data recovery runs quietly, but nothing comparable to specific programs (which unfortunately are paying).
And free and works the way it is, if we want the actual license (no charge), we must register via email.
