-Install the new disk in the SME Server while turned off, then boot it up.+:!: We also use this technique in virtualized server installations.  For example, if you create a VM using a single large virtual disk, you may easily get to a point where you can't snapshot it due to lack of free disk space.  Using this technique, you can temporarily disconnect the second large 'data' disk, take a snapshot, then reconnect the virtual disk when done.  Just one of the reasons why you should use (expensive) shared storage for your virtualization projects...
