Making /Exact/ Duplicates of Disks

[dimo414]

So I've wondered for a while why you can't just copy a disk bit for bit and have it work, then I found this topic: http://forum.imgburn.com/index.php?showtopic=4875 where someone seems to imply that is in fact not what image burn does! Which would certainly explain that problem. Is there any software which can do that? Literally rip every bit and create an identical iso file?

 

In case anyone's concerned about piracy, I'm just trying to make it so I don't need my physical cds to play games, won't be distributing or anything. And yes, I know there are game-by-game resources for this sort of thing, but it seems there ought to be a way to just make an file which is for all intents and purposes identical to the original disk.

Burned discs can have the same logical arrangement of a pressed disc, but they can't have the same physical properties.

 

For example: some copy protections try to read the ATIP and/or other properties that only recordable media have. Other protections rely on a purposedly made out-of-standard pressed disc that, when you try to copy, will give wrong/bogus information or will simply refuse to read at all. These are only two examples: there's a s**tload of different copy protections and no software can circumvent/bypass all of them

Interesting. That's unfortunate. It seems it would still be possible though to copy that physical data if you just copied literally every byte. Obviously that's harder than I imagined, but still...
