Practice ten minutes because the DVD burner Plextor has not been recognized. Cause of the problem was that the IDE and the Voltage Connector only with violence on the burner were side by side insert, ie no scope millimeters. If the voltage connector would be slightly less wide (0.5 mm is sufficient) it would be super. W7 was configured on forever without finding the burner. After the violent intervention of the burner has been identified as LW, without zusätzlicheTreiber- installation and running. The enclosed CD SW PCClone Ex Lite + refused to uninstall from the Control Panel, had to be removed with tricks.
