For some reason, my NEC 3500 and 3520 keep unchecking the "enable cd burning" in the properties for each drive. I recently upgraded my mobo and dvds burn with no problem but now when I try to copy a cd with either Alcohol 120% or Nero, the programs abort and I have to go back into the properties and enable cd burning again. I've tried uninstalling the drives and reinstalling the software but neither made a difference. What else can I do? I've got a shitload of cds to burn and it's gonna take me forever if I have to keep enabling manually. thanks in advance.
