I want to back up the hard drive of my laptop to an external hard drive (160 GB). What is the right way to do it? Shall I copy paste the folders to the new drive or go to START>PROGRAMS>ACCESSORIES>SYSTEM TOOLS>BACKUP ? If the hard drive of my laptop fails, will i require to reload all the softwares I have in it? I do not have a hard drive imaging software, which I guess clones the hard drive of your laptop. If I have that software, will I still the need to reload the softwares or not?
