Newbie question: I've seen software that can create a set of bootable spannable DVD's for restoring laptops. However, since Vista and installed software is like 50GB, I was wondering if there is a way to buy a Maxtor external drive, and use True Image to create a bootable external restore drive? Lets say my hard drive gets really destroyed. Can I simply plug in an external USB or Firewire drive, and have it magically restore the entire OS back to the way it was? What kind of external drive do I need? What kind of software do I need?
