Go to Computer --> C:\ --> Properties --> Hardware (Tab) --> Select HDD in list --> Click the properties button (bottom right) --> Policies (Tab) --> Tick the first box, and even the second, according to your needs.
Note that the first one should already be checked, hybrid feature is enabled by default on Vista...
