Re-install to the original software that worked. If it no longer works, that's a good sign that the drive is faulty.
I own an Alienware Area 51 m766 system with Windows XP SP2. I updated Nero 6 to the latest version and it's stops burning after a few seconds without explaining the error. I tried with other burning software and does the same. Nero support told to try different brand of CD, to install Nero 7 and nothing works. They even suggested to update the burner firmware but Alienware recomends not to because I can permanently damage the burner.
It worked fine until I updated Nero 6.
I'll appreciate any help you can give me.
