I'm asking this here, since I can't find a more appropriate TA.
I've heard about some techniques to manipulate the image of a CD (using a hex editor) to change the name of a folder in a way that it contains some illegal characters (like slash and backslash). I've seen the result. You can't copy or open that folder, while some programs can do.
So lets break my question down to parts:
1) How can I do that with a Hex editor? Are there online tutorials etc you can suggest?
2) Is it the best method to "lock" a CD from being copied? Or are there better ways to copy-protect a CD?
