I have a FW HD currently formatted for a PPC Mac. I want to reformat it so that it can be used to start up an Intel iMac (GUID partition table). Ideally, I would like to give it two partitions, one to back up my iMac and another to back up data from a PC in my lab. Will Disk Utility allow you to format one partition as Mac OS extended and another as MS DOS? If so, would this do what I am intending?
Second question. If I have a GUID volume on a FW drive, can Migration Assistant be used to copy over everything on the iMac to the external? If not, can I clone an Intel Mac volume with Carbon Copy Cloner?
