my worry is that when i completley wipe my c/drive of xp for the full install of vista should it go wrong,(i hope not) that my ghost image on d/dive wont work as it no longer will have ghost on my computer as it will have been erased, P.S I bought xp home last year and had problems with hardware ,after reinstalling windows severall times to my surprise it suddenley refused my key, after world war 3 with bill gates associates they activated it for me only to tell me i had used the product key to many times and it was invalid so if in the future i needed to reinstall windows i would have to contact them to do it ,i was not impressed, i do not want to go down that road again. thats why i partitioned my drive , installed ghost and saved the image on a seperate patition so i can go back as many times as required
