HI

What would be the best software to use for cloning a hard drive in a SME which currently uses about 15 computers?

We use Symantec Ghost (http://www.symantec.com/home_homeoffice/products/overview.jsp?pcid=br&pvid=ghost10).

Here a link to free programs that I have not tried but the site that recommends them is trusthworthy in my opinion:
The Extended Best-ever Freeware Utilities List (http://www.techsupportalert.com/more/extended.htm#95)

GHost ans Acronis True Image are consider the top disk imaging tools.
