Early on when I got my 107D, I didn't have much luck with the 1.10 hacked fw. I moved to 1.12 and 1.13 and then back to 1.10 hacked. In the mean time I cleared up a driver conflict. Of all the things it was an Epson printer driver conflict. I installed a newer driver and now I have much better luck with the 1.10 hacked fw. I can even copy on the fly at 6X, using 4x rated Memorex (ProdiskS03) and even some 2X rated Imation (Ritek G03) media. Both my source drive, a Lite-On combo drive, and the 107D are on the same IDE channel. Is this about the fastest I can copy on the fly? I mean at 6X? I'm wondering if anybody is able to copy at 8X on the fly.
BTW, I don't know how the source drive is able to keep up with the burner at the beginning of the disk. My combo drive starts reading at about 3.5 at the beginning and at the end it is up to a little over 8x reading speed. But somehow, I can burn a full disk in about 11 minutes. My guess is that the burn speed at the beginning is less than 6X.
