My PC only has one ATA connection for a HDD. I want to upgrade the existing HDD by making an image of the existing HDD. Can I create an image on an external HDD, boot using a TI boot disk and the NEW blank HDD and restore the image from the external (connected via firewire) to the new HDD? Also will making the image on the external delete anything else on the external I have saved? I am sure these are total newbie questions so thanks for your patience!
