[I bought https://www.microcenter.com/product/617582/powerspec-g705-gaming-computer that does not have a 5.25" internal drive bay. I bought a SATA2USB 3.0 external drive enclosure in order to use my existing internal Blu-Ray Writer] My first write to a BD50 generated an error. Windows 10 was up and running and I just pressed the power button on the drive. After this, I restarted the PC and was able to get a successful burn. One guess is that you need to power the drive up and then start the PC? In any case, I just wanted to get some feedback from using a USB optical drive in general. I attached the log file from ImgBurn with the file extension of .txt so that it could be uploaded here. This seemed easier than copying and pasting - taking up a lot of space here. EDIT: I forgot. I also reseated the cables, both power and USB connections. EDIT2: Even if I power the drive enclosure first before powering up the PC, I still get issues from the PC trying to find the drive? I have had to power down both, reseat the USB cable in the PC, reboot and try again. I would love some feedback about using USB optical drives.
