Clone Hard Disk Software [duplicate]
EASEUS Disk Copy is a potent freeware providing sector-by-sector disk/partition clone regardless of your operating system, file systems and partition scheme by creating a bootable CD. The sector-by-sector method assures you a copy 100% identical to the original. Disk Copy can be used for copy, cloning, or upgrading your original small hard drive to a new larger drive. Simply speaking, it can copy anything from the old hard drive including the deleted, lost files and inaccessible data.
Might have a look at clonezilla.
