Shoot, I didn't realize they linked to manufacturers' sites for the files 😱
I'm trying to look for it on my drives, I flashed mine from OS06 to OS0B just a few days ago. I didn't notice any difference, but maybe it could fix the problem you're having. Mine burns entire CDs in about 5 minutes. What burning software are you using?
edit- stupid me, Nero comes with the drive.. Nero is generally the best you can get, so shouldn't be Nero causing problems. Do you have anything that could conflict with Nero, such as DirectCD, or even InCD?
