Ok, I have been reading a lot of issues associated with the N440 burner but my situation is a little unique. First of all, let me give you a little info on my system
P4 2.66 Ghz
845PE Intel Chipset
I recently installed the drive and installed the ROxio 6.0 software along with it. I installed the software and all the updates from the web.
When I try to burn files from my hard drive to a DVD-R disc, it starts writing at 4x for 10 secs. Then goes to 2x, then a few seconds later, it drops to 1x and then eventually the light goes out on the burner. After 5 mins of nothing happening, the disc ejects and I get a buffer underrun error. On the software, buffer underrun is checked off. I have also tried the disc that came with the drive and it does the same thing. I have tried several configurations (slave, master, CS, IDE1, IDE2) and no success. I have called TDK and they believe that is has something to do with the intel chipset of the bus mastering, anyone have any simular problems or ideas?
