Its a Sony DRX510-ULK, USB2 and firewire, all formats burner. Pretty good spec apart from no dual layer. I bought it for use with my laptop, but I'm buying a desktop for normal use, so would like the burner in there. If I can avoid speccing a DVD burner, it would save me a fair bit, and also give me more flexibility in searching for a bargain. So any idea if I can take the drive out and put it in a drive bay?
