Hi, thanks for your reply. It is a slim-drive. I did do the search for firmware via imgburn and that what brought up 256 results. I've always been able to burn single layer fine with the drive, so it is really annoying that I can't burn a dual layer blu. This may sound dumb but Is there any firmware that i can try, like a universal one that is compatible with most drives or something? I don't really want to go to the expensive of buying another drive or different blanks when it's not something i'll be doing that often
