I have an LG BH16NS40 drive. The first one stopped burning BD discs so I returned it and got a replacement. The replacement worked and I managed to successfully burn some BD discs. Now, it just failed to burn any BD disc, like the previous drive, but does burns DVDs.
The latest attempt kept giving me "Invalid Address for Write", whilst other attempts seemed to go well but it just left me with an empty disc at the end. I've tried with Verbantim and some Phillips media, but both have been unsuccessful (they did work when the drive was new, though).
I have also noticed that the BD disc has scuffs/scratches that weren't there before I put the disc in the drive. The drive appears to have put them there during the burn, which I find a bit odd.
It seems like this LG drive is just bad, and now it's out of warranty it looks like I wasted £70-80 at the time, since I am left with a very expensive DVDRW.
Is there no hope for this drive? All I did was not use for a while, since I also have a Sony DVDRW which I use for general use, and haven't needed to burn any BD discs for a while. The simple passage of time, not wear and tear, seems to kill this drive's BDR abilities.
