I just recently had bought a new Seagate 500gb 7200 HD. I have it already installed in the enclosure and hooked up to my computer via firewire 800 and already have Carbon Copy Cloner installed and working as well. When I go to use CCC the drive doesn't show up. I guess that means I have to format first right? In the device manager window that comes up when you choose to initalize, I chose the drive and then I went to partition and then did the drop down to 1 partition. Then under options, you can choose a partition scheme, so I read all 3 options. The default selection is "Apple Partition Map" but it seems like I should choose the first one listed which is "GUID partition Table". Which one am I supposed to go with? Also is there any other things I have to select or do after that to clone the drive?
