I've got a Samsung Writemaster DVD burner. It burns at 16x, but in the last few months I've noticed that it has started getting slower and slower: it takes the same time to burn at 16x as it does at 4x or 8x. A guy on forum suggested that I uninstall the secondary IDE drivers on my PC and then reboot the computer, but I'm not sure about that. Is it safe? Does anybody have any ideas about why the burner is going slower? cheers.
