Your desire is to...what?
If you want to put a blank cdr in there, and write to it like dragging and dropping files to another harddisk, you need to install packetwriting software
Nero, by itself, does not do this, but instead, you need to install the packet writing software called incd, then format the disk, then drag and drop it
Or, you put the disk in, use the nero normal software, copy the files into the explorer-like window, and it opens and closes the disk during the burn
So, what are we trying to achieve here?
