It may be worth your while looking at partimage (which can also image whole drives). It only copies used sectors so avoids the problem of storing obsolete data. I believe Clonezilla uses partimage, and you'd have to use a live CD to image a system drive like this anyway. -- Neil Bothwick War does not determine who is right -- only who is left.
