Hi! I am wondering if I can use this product as a copy of my hard drive while I travel? I would like to copy my entire HD onto a Backup Hard Drive and then hook up the Backup Hard Drive to a laptop to access the info. I have read about cloning vs imaging and think I want a clone - but can you provide more info? Steps needed? Precautions? Also, I read somewhere "Make sure your disk imaging and backup software can restore the image of your old computer to new, dissimilar hardware." Can True Image do this? Many thanks!
