This can be done booting a linux live cd, I found a good tutorial <a href="http://www.irongeek.com/i.php?page=security/localsamcrack2">Here</a>
Sometimes it also works if you plug the drive into a new computer that is running its operating system off a different drive. In this case your drive would act like a slave drive (make sure bios boots to newer drive) then you can just drag the files over.
