Well I solved (avoided...) the Event ID: 11 mess by removing the nVidia IDE drivers. Windows is now using it's own IDE drivers. But now ATI 10 Home gives the following error, when I want to make an image of the system disc to the data disc: >>> 0x70021 Cannot access drive. Cannot create the image of the logical drive C: because it is currently in use by running applications or the logical drive contains bad sectors.: None <<< Does anyone know why this happens and what to do about it? I can solve it by re-booting and make an image right after the system is up again, but it should be possible to do that with running applications. And to make it more puzzling: sometimes it does work with running applications.
