Nero doesn't recognize my DVD Burner

I had a DVD Burner which I used a lot with Nero 6, after a while I needed to plug it out, and now when I plugged it in Nero just doesn’t want to recognize it! I plugged and unplugged it a thousand time and nothing.
It works well when I put a disc in it and all that.

What should I do? Thanks.

Try a new cable! Your drive is bad or the connections I suspect! Update your BIOS and IDE drivers from your MOBO site! Go into safeboot device manager and look for hardware you no longer have!
