top-dawg,

You will need a working guardian OS unit to load a bare drive. The 4500 uses a Watchdog BIOS, and will try to boot all 4 drives if pressent. It's very strait forward, but you must have all of the diaster recovery (snapshots) and AV disable to make the transfer. This is the reason it's hard to find someone willing to tamper and change server settings to prepare a bare drive not for their system. As with all systems if you don't do it right you will loose your data. The guardian os takes up 10 gig of drive space + data space.
