I am trying TI. Just got an external HD to which I want to back up (image? Mirror?)my 40gb laptop hd. I partitioned and formated NTFS the new HD so the first partition is 42gb (room for the whole laptop data) and a second partition for everything else. (I have Win XP SP2) I created a rescue bootable disk and put it in a safe palce. Now I am ready to do the backup (image? mirror?) and I do not understand what the menu is asking me. First: Why would I want a Secure Zone? And won't it mess up the partitions I made?
