First off, thank you very much for your quick response. Now for a few more questions:)
Where in Nero is the option to view the true speed of the drive?
DMA is already turned on. This was the first thing I checked.
As far as the 80 wire cable, I would assume it is the right one. It's the same one the primary cd-rom was on when we got the computer. It's a Dell Optiplex 520.
They are on the same cable and I will try switching this. Should I put the Cd-Rom and the hard drive on the same channel or the DVD burner and hardrive on same channel. Also which do I set as Master and which as Slave? I'd assume the Hard drive still needs to be on the primary channel but I'm not certain.
Once again. Thanks in advance for all of your help.
