I bought this drive specifically to copy Blu-ray discs and unfortunately this drive didn't load Blu-ray discs. CDs and DVDs loaded and copied without any problems, but the only thing that happened when the BR was inserted was repeated clicks trying to mount the disc and eventually ejecting it. Most likely a bad block. But I wasn't overly impressed with the overall build quality of this unit (and that's probably the case with many of these very small portable optical drives). They seem flimsy and I imagine loading and unloading hundreds of discs would take a lot of effort. I decided to buy a big, solid LG BR internal drive and a nice, solid case for it - and for about the same price I got a much more reliable (and respected) work drive that I'm much more comfortable with.
