Hi, I want to clone my hard disk to an external USB drive and keep it safe and ready for use if my laptop hard disk fails. But reading the help and instruction manual, I get the bad feeling that once I've cloned the disk, I have to then set it as my primary and install it in the laptop. So I know it might seem ridiculous, but could somebody please just reassure me that cloning the disk will leave it unchanged and still functional in its current location, i.e. as my main laptop internal drive? Thank you from a TI newbie.
