I currently have the stock drive that can only burn CDs etc. I want to put a new drive in it, because I have been burning dual layer DVDs on another machine and I won't have access to it much longer. From what I have seen the UJ-857-C drive will fit in my drive and burn dual layer DVDs. I haven't been able to find much info on replacement drives via google so I am wondering is that the best/most stable drive available?
