Copy protection question: Often quoted here in this forum: Some companys try to copy protect their CDs by modifying the lead out area. Someone suggested to place 2 audio tracks at the end of the data track and manipulate the lead out so it starts in the middle or end of the first audio track.
So far, so good, some drives can't sector-read the second audio track (SCSI message somethings like (sector out of range) and therefore cannot copy it. All fine. But how do you DETECT if that stuff is missing if your drive cannot read it? I tried 5 drives and only one could read past the "to early starting" lead out. And why using audio tracks and not data?
Or am I misunderstanding something? Where is the sense if I put data in the lead out that can most of the time not be copyed if I cannot read them?
