In my laptop , a few days ago I've noticed that my CD/DVD writer isn't functioning properly. When I've started any burning job with nero express, I've noticed that buffering is going on..okay, burning is going on..okay, at the end, a message have come.."Burn process failed" and my CD/DVD is still blank. later on I've reinstalled my operating syster(win xp) and i've used nero 9 and alcohole 120 but the result is the same. All process is going on smoothly but when the burning progress bar is about to end..the message "burn process failed". What kind of problem is this? Will somebody expert/techie here kindly give me a solution/clue? By the way-my notebook is HP6530s and it is 5 month old. Thank you all for your time.
