I have purchased a Dimension 3100 with Dell Datasave & 2 80gb SATA running raid-1 array. It also has Norton Ghost 10.0  installed. My question is why need ND Ghost?  The raid-1 should have a mirror disk in case of one disk is crashed.  I can't run the GHOST 10.0? It said I need goto web site to activate? Does it come with full license or just 30 day trial license?
