Question: does anyone know what model power supply I can use with the BDR-XD05. My player keeps cutting out
Document: I bought the white version (BDR-XD05W) at BBuy. The clamshell design makes it very compact. Reads blu-rays perfectly with single USB 3 port on my system (MBP15 retina). I haven't used it for burning and don't know if it will write without using additional power from Y-cable but that's not a priority for me.
Nice looking unit, good quality. Flexible power (USB or power supply) but no power supply included, this is a little draw back.
I have tried several solutions for burning a BRD on my MacPro (so, I'm reviewing the BDR-XD05W). Like the previous reviewer, I saw this at BBuy and purchased it hoping that this one would work.Did I get it work work, eventually? Yes. But the limitations of this drive make it hard to recommend.First, you must tie up 2 USB3 ports. This drive will not have adequate power on a single USB port.
If you must use two USB 2.0 ports that are far apart (like on the right and left sides of a laptop) then you will have to connect a USB extender cable (not supplied) to one of the ports.The unit's cover opens to about 75 degrees for easier disk loading and unloading, more than the approximately 30 degrees shown in the picture. Also, the pushbutton that opens the cover does not work unless power is present.
I bought this product for occasional use watching movies, burning backup disks, and installing software from disks with a laptop that does not have a built-in optical drive. So far I've successfully watched a few movies on Bluray and DVD and burned data on both types of disks. A Y-cable is included that connects the unit either to a single USB 3.0 port on a laptop or to two USB 2.0 ports.
I had a different brand before where you slid your disc into the slot, the device grabbed your disc and pulled it in. That worked great EXCEPT in the case where I needed to manually eject the disk. There was NO pinhole in which to stick a paper clip to do the ejection! This device does the clam shell! It works beautifully as a CD player/burner AND you will never be stuck with a stuck disc!
I cannot comment on reliability or longevity as I've only had this unit for a few weeks.
The Pioneer BDXL burns, reads and does all the needed functions at an acceptable speed. I am very pleased with the performance.
At first, it looks very cheap and I was thinking that it will not last much, but fortunately I was wrong and after a couple of months it still working perfectly and I am happy with my purchase.
Still, if I could get it to work, I'd make the sacrifice. My Macbook Pro Retina has two USB3 ports, one on each side. The drive comes with a two-connection cable, but it's only 18&#34; long, and the double connectors require that the ports be side by side. In short, won't work with a MBPRetina, and to make it work on my MacPro would require a much longer cable. The other solution is to purchase (separately) an AC adapter.
Answer: The supplied USB cord has two plugs on the end that's connected to the computer.  Don't understand why but I've successfully used the burner while hooked up to USB3 port.  Might have something to do with the data transfer speed in addition to more power.  Or maybe the extra USB (and 1 or 2) is used for powering the unit while the USB3 is for data.  Just an idea.
