Description

When dumping a CD with multiple tracks (one data and one audio), Aaru's dump doesn't match DIC's right at the start of the second track (which is audio). These sectors are mostly 0'd out in Aaru's dump, but contain data in DIC's dump. I believe other CDs are affected as well, but I would have to go through them to be sure.
