Hello, I have sony dw-d22a flashed to sony dru-710a, my recorder worked fine about six months. Now it can only read and burn DVD disks, and it don't recognize CD-R's! My friend told me to recalibrate my writer. How to do this?
You probably should not try to "re-calibrate" the drive. One thing that you may want to try is cleaning the lens inside of the drive. You will have to open the drive and use a very soft cloth to wipe the lens. If you can, get someone who has done this themselves before to help you.
