This is my deal. I have everything on c:. I do a full backup (image) only to an external hd. What is the edge in upgrading to 10 The only thing I can think of is that perhaps the new boot disk under 10 may have additional drivers making the boot disk under restore faster. I'm happy with 9.1 but if the restore is faster......over one hour in 9.1. How much faster if in fact the drivers on 10 are upgraded can I expect. I use Maxtor III one touch. Any comments are appreciated.
