I have Win 7 and wish to replace the hard drive in my HP laptop (my first time trying this). I downloaded Aomei Backerupper to make an image of my current HD. Plan was to use a USB drive for the image, but I have about 150 GB on the current HD. Question is, can I use multiple USB drives to create the image clone (the way new computers used to be sold with multi-disk sets of the OS)? If not, how do people make images of large HDs on removable media?
