No problems with copying CD's at all. Of course, because of the IDE limitations, whenever I use Nero 5.5 to copy a CD, I get a message that recommends that the two drives be on separate channels. Now that would be fine, but I don't want to liimit the hard drive speed by setting up the Pioneer as a slave on the Primary IDE channel.
However ... I have not encountered any errors or buffer-underruns as a result of having both drives on the same cable ... and the burn runs at full speed (16x).
I am currently listening to an audio CD that I burned just a few minutes ago. The CD was a retail version of Diamond Rio's "Unbelievable", and totaled 356MB. The burn and the TOC took 3:16. The CD sounds great. No skips, no clicks, no jitter. I'd notice, too ... because I was a professional musician and sound tech for twenty-five years and my ear is pretty good. Or so I've been told. I'm still in demand for "washing" out stage setups. Of course, everyone could be deaf. <GRIN>
Note: The media was bought in bulk, Memorex 16x multi-speed. But I've also had good luck copying at 16x, even with 12x media. BURN-Proof is really good stuff!
