[qanda]This thread is about the Optiarc AD-7170A. Click here to see full specs[/qanda]My computer is almost 2 years old. I bought it with a Optiarc DVD RW on it. I used it every day and i never noticed that my DVD doesn’t work. We only used it for CD-s. Burning as well as reading.
Yeasterday I put a DVD in it and it didn’t read it. It doesn’t read any. I checked its property and noticed regio 1. I live inGermany, so I tried to change it to region 2. But I got error message: “DVD region change error”. I was signed as administrator.

Hi and Welcome!

could you please try if you can boot from a bootable CD/DVD?
Also please check if there are any error notifications in Device Manager.
