I just picked up this drive and it seems to be struggling while copying audio discs.
The “Used Read Buffer” drops from 100% to 0% after burning for about 2 minutes. Then the Smart Burn kicks in, shuts off the burn process, the “Used Read Buffer” builds up to 100% again, and then this whole labored process keeps repeating itself.
My old lite-on 24x12x40x didn’t do this, which was connected exactly the same (burner set to master on secondary channel and DVD/CD player set to slave on Primary channel). UDMA is enabled on my DVD/CD player as well as the CDRW. I flashed the CDRW drive to the latest firmware, flashed the mobo to the latest BIOS and upgraded to the latest version of Nero. I’m at a loss.
