I read it carefully and I will take your suggested approach. It is not simple but what I understand it should work. If everything is fine I will write a short manual how it worked. But my earliest possibility is in two week to do it, so please be patient for the feedback. But before I will do this I have to buy another harddisk to make a backup before. As I have critical data on it I must avoid any date lose. Thanks and you will hear from me, if it worked fine.
