CloneCd solve protection in PSX games?

[gargoyle_1976]

Something isnt very clear to me. I read DaemonTool faq for protection on PSX games and CloneCD can make same copy of PSX game. This can be done if you have CD-RW which can read and write RAW+96 metod (read/write SubChannel Data). That mean that CD-RW can rean subchannel data.
1. Is copy create with CloneCd same as original?
2. What about non-protected games?
3. Non-protected games havent subchannel data?
4. Or we stiil need MOd-Chip and why?
5. Because of subchannel data or boot protection?
6. Why to use CloneCd and make copy of game with subchannel data when we have Mod-Chip?
7. What about "Read Error" when I put Ignore?
Thx
