I run my Mac mini from an external Lacie 160gB firewire drive. It's 10.4.3 at the moment. The internal drive is also 10.4.3. I know there used to be issues with updates when external drives are connected. 1. Should I just risk a 10.4.4 update as is, or 2. Should I clone the FW drive to the internal mini HD, unplug, update, and then clone it all back to the FW again?
