Slimtype DVD RW SOSW-852S PSB2

This is what I have in my Averatec notebook. Can this drive burn onto DVD+R DL discs? Do I need to flash the firmware on the DVD drive? I’m a total noob, and trying to figure this stuff out. Yes, I’ve googled it, but I can’t find the information I’m looking for. I’d really appreciate some help… Please and Thanks.

Hi and Welcome!

get Nero Info Tool and check the capabilities of your drive. It will show you what kind of media is supported.
For DVD+R DL, stick with Verbatim, since these are the most reliable at the moment.
And - forget about firmware updates for notebook drives, unless the manufacturer of your notebook offers some.
