How does nero verify discs

I’ve done some goggling and haven’t come up with an answer. I’m just trying to figure out how reliable it.


Nero Cd speed is very good tool to see the quality of your burned media.

I’d assume it does a bit by bit comparison of the source file to what can be read back. However, because the disk has error correction, this is not an exact comparison of the disk contents, as error correction could have occurred when reading the disk.
