I don't finalize my discs and Windows Explorer can read them. What type of disc is it? (-R, +R, etc.).
Is it only this disc that causes the problem?
Not that it matters, but I don't see where Nero InfoTool has "disc status". Mine has a disc tab, but it doesn't mention status.
Do you have Roxio Easy CD Creator installed?
Apparently that "Incorrect Function" message can pop up for a variety of reasons. It's probably not your problem, but sometimes it's fixed by going to the Drive letter in Windows Explorer and right clicking on it. Go to Properties; Click on Recording; Check "Enable CD recording on this drive".
