Basic question about BWA

This is the probably the most basic of questions but what does the bwa file actually do? I know where supposed to have a graph with as little spikes in number and size but what does it do? Does it hav something to do with the cds protection?

Well, accoring to here, ‘The linear sector density of Securom discs is very different to the density of normal cdr(w)s.’

Basically a BWA stores this information so it can be applied to the CD or image to try to make it seem as an original.

People, please correct me if Im wrong. :slight_smile:
