I realy don't get it.... dose the original CD work or dosen't it work.
If you got problems to do a backup with a 1:1 copy tools. Do it by your self. But it wont work 1:1 but you can be shore the files you writed can be read.
Copy the hole CD, to a map in windows, then open Nero and label the cd as the original CD has, and copy over those files that's are in the "windows" map on the harddrive and Burn!
