I am sorry, but dont understand your question.
You mean, you want to make a working backup from the "Icewind Dale 2" Game ?
If thats what you meant, i would recommend to download a tool which detects the copy-protection and use it with CloneCD.
The newest program is called SCOUT.
You can grab it right here:
