How exactly do you do that, delete and re-install IDE channels? In device manager under hard disk controllers, I have a standard dual PCI IDE controller and a primary PCI IDE (fifo) controller which are working fine. But, in 'system information' under 'problem devices', it also shows a secondary PCI IDE controller, which says has been disabled. I wonder if this has anything to do with it. Even though it's not my hard disks causing trouble. There is a check box for my hard disks for DMA, just neither of my other drives, one a DVD drive, the other my burner. Any ideas. I also read that if I burn at a slower speed, this might rectify it?
