Go into Device Manager, expand the ATA/IDE Controllers, double-click on each of the two controllers, go to the Advanced tab and select the mode you want (presumably UDMA2 for the burner). If the setting refuses to stick, maybe you have bad IDE cables that are getting lots of data errors. In that case, switch to some new flat 80-wire 18-inch IDE cables, do an Uninstall of the Primary and Secondary ATA controllers in Device Manager to reset Windows' circuit breaker, so to speak, and see if that fixes it.
