Clone a Hard Drive Using an Ubuntu Live CD
 

Whether you’re setting up multiple computers or doing a full backup, cloning hard drives is a common maintenance task. Don’t bother burning a new boot CD or paying for new software – you can do it easily with your Ubuntu Live CD.

Not only can you do this with your Ubuntu Live CD, you can do it right out of the box – no additional software needed! The program we’ll use is called dd, and it’s included with pretty much all Linux distributions. dd is a utility used to do low-level copying – rather than working with files, it works directly on the raw data on a storage device.
