You should be able to copy the cd using the copy command. Allow the CD burning software to make it's own image file for the CD.
I am not familier with Nero, but EasyCD has a checkbox to copy files to the HD.
You could set the number of copies to 2, and just cancel after the first copy is made.
I have also had problems with reading a few CDs copied from HD image files. I have 1 CD that just will not work when I copy the files from a folder on the HD. It only works when I use the copy function.
Shut down all unneeded background applications before burning the CD to reduce memory and system load.
Keep in mind that some CDs just cannot be copied.
