My System: Dell dimension 2400 desktop. everything stock, except a plextor dvd rw drive. this system is about 1 and a half years old. and its running windows xp- home edition. The drive i bought off of craigslist. So i got home and installed the plextor drive about 2 weeks ago. it plays dvd's without any problems. But it wont back-up any dvd's because it says they are copyright protected. I just want to back up my movies, because i am hard on them. The only software for burning them i have is roxio/sonic program that came stock on my system. Is it possible to back them up? Ok the main problem now. Like i said, it plays dvd's and data discs fine. But when i put an audio disc in, nothing happens. So i went into my computer and right-click open. it says the drive is unaccesible due to an I/O error. this just stopped working about 2 days ago when i defragged and disk clean-up'ed my computer. It doesnt make sense that audios arent working but dvd's and data discs are. And i checked the plugs on it and they are all firmly in place, and no bent prongs or whatnot. physically, it seems to be in good shape.
