Hello everyone. I want to consolidate my cloned OSes so that I don't have to hold on to multiple external HDDs. On a 1TB WD firewire400/eSATA/usb 2.0 I currently have a backup of OS X Tiger, and OS X Leopard. On my former internal 320GB WD HDD, I have a clone of OS X Lion. My question is, can I copy those clones to separate partitions one one drive regardless of whether it is formatted as Apple Partition Map or GUID? The reason I think this could work is because I have my original MAC OS X Leopard installation disc from my iMac that I can boot up either a PowerPC or Intel Mac with and use disk utility to erase and restore each individual partition. Does this make sense or is the partition scheme very essential? My goal is to have all of these clone copies on my former 320GB WD drive that I connect via usb when it's in a bare drive docking station. Thanks in advance for any advice, and please feel free to ask questions if this post seems confusing in any way.
