Never assume that this will work, because hard drive manufacturers cannot count. i.e, whether a "2 TB drive" is actually 2^41 bits in size depends on how much space is being used for error correction, bad sectors, and the like. Many open source and commercial cloning tools will do a *much* faster and more efficient duplicate. > The current drive is the conventional harddrive.

It's when you mount them both physically on the same hardware at the same time that hilarity can and will ensue.
