Not all controllers can build a new array on the fly. Even with those that
can the process is not very intuitive. It is very easy for someone not
familiar with the process to accidently erase the existing drive. It is also
very likely that if the array is built successfully Windows won't boot until
the driver is installed by booting from the Vista DVD which again is not an
intuitive process for many people. Changing from one drive to a mirror is
not a trivial task for most people. You are assuming everyone has your skill
and knowledge. Without knowing which controller the OP is using and their
skill level erring on the side of safety is appropriate. There is a very
good chance of data loss and a possibility that Windows may need to be
repaired or even reinstalled if something goes wrong.
