Wow, that's one old optical drive! Are you sure? According to an
article right here on Tom's, it's an PATA (IDE) drive from ca. 2006?
If that is the case, then a good chance is that it's not recognizing the media that you put in it. There are DVD ROM and DVD RAM and DVD R/W types of media. I've not done the research to check which media types your drive can burn, but that's where I would start looking.
