Sorry, I been posting on this topic a lot but I am getting CS3 soon and trying to fix an error with the partition information. Basically requiring the partitioning and formatting of my HD. I have a USB HD that I used CCC to copy the files into it. Can I just boot off USB HD and use Disk Utility to clean the HD on my mac pro and just copy over the files. I tried doing Image option in CCC but I do not have USB HD bigger than 160gig. Any help is appreciative. CCC=Carbon Copy Cloner Thank you RM edit: Or can I use Migrant Assistant to transfer everything to one HD to the other?
