Well after Gemma's laptop got a Vista Bug which meant all it would do was boot up into a black screen with with a moveable cursor I decided to finish building my nas. After some head banging I got samba working properly so we have individual private folders and I public one to share stuff. I managed to get the documents off her old disk and moved them onto the nas. Rebuilt vista on the laptop and set all the windows documents shortcuts to point the relevant folders on the nas rather than on the local drive. So if laptop ever crashes again all have to do is reinstall the os and relink folders without having to worry about data recovery etc.
