Hi Viktor2002, welcome to the forum. It would help if you tell us which burner you're using. It could be a problem with your burner or some other software problem. If you want to know for sure you can, for example, try your drive in another computer and see if it works there. Some drives, like the Plextor drives, offer a self-diagnostics test which may also provide you with some usefull information. Please report back with more details on your burner, hardware and software.
