Free drive cloning software

[Morningside]

I need to clone a drive so that it's exactly the same and boots as well. I have a USB to SATA connector so what is the best free software out there?

I know I can type this request into Google but that usually returns spyware and other unwanted crap.

DD? Well that sounds a bit complicated but willing to try anything. Will report back tomorrow with my findings of how I get on (hopefully!)
