I have a NEC DVD Burner model ND-3520AW which has been burning both CDs and DVDs fine for the past 3 or 4 months but now it won't read any of the Data DVDs I burn even after reporting that they burned successfully. * I have tried burning at 2x, 4X, 8X, & 16x. * I have tried using Maxell DVD +R 8x and Memorex DVD +R 16x media of which I had always used successfully in the past. * The burner will read data DVDs that I burned several weeks ago and retail DVDs of popular movies. * The burner will burn and read data and music CDs * I have tried using 6.016, 6.018 and Nero.v188.8.131.52b.Premium.Edition I'm all out of ideas fellas. Can anyone offer any suggestions of what my issue might be at this point? Any thoughts/suggestions would be greatly appreciated.
