I have a Mashita dvd-ram uj-850 ata-drive that is not working properly. The drive is recording dvd-rw and cd-rw but when it comes to dvd-r or cd-r is not recording them. The cd-r or dvd-r starts recording but it gets to a point where I get this message: "blank media cannot be detected" and it stops recording. I have tried everything that has been posted in this websites, going to the registry and deleting the registries, I have also gone to the microsoft website to have it diagnosted and according to the web site it has been fixed but the problem is still happening.
