About a month ago I bought a DVD burner (Optowrite DD0405), and it never burned a DVD. Power Calibration errors always came up. I tried a few different kinds of media, and none of them worked. I was told that the drive may be defective. It was still under warrenty, so I brought it back and got a new drive of the same model. This one has the same problem. I was wondering if anyone could help me before I decide to trash it and buy a new model. Is it possible that both drives are defective? Maybe something is wrong on my end. I dunno, but any feedback would be apprecitated.

Thanks
