Help buffer underrun during NOLF Back up burn

[Feet]

I have two programs to burn Adaptec Easy CD - Creator 4 and Nero Burner 5 but I couldn't copy No One Lives Forever as it said their might be a buffer underrun. I have wastd many disks. It says that both drives are connected to the same IDE Ribbon and I was wandering if I bought another cable and connected it up would it work. Also if so how would I do it. Thanks very Much.
