[help] CD Burner Problems

I have a HL-DT-ST CR-RW GCE-8320B. It has recently stopped working. It can read CD's and see that they are there but if I try to burn in iTunes I get an Error 4000 message and if I try to burn in Nero it freezes around 7%, making the CD useless (I have wasted a lot of CD's that way) Anyway, I looked for some drivers and couldnt find any. Anyone else here have this problem and fix it?
