EASEUS Disk Cloning
EASEUS Disk Copy 2.0 is a freeware program for cloning a hard disk. It makes a sector-by-sector copy of your hard disk ensuring the copy is 100% identical to the original. It is useful for upgrading your hard disk to a new larger drive.
Disk Copy 2.0 comes as a zipped ISO disk image. Burn the ISO file to a CD, boot from the CD, and you are ready to clone a disk. Because it runs off a bootable CD, it works with any operating system. Disk Copy 2.0 supports IDE, SATAI, SATAII, SCSI, Firewire (IEEE1394) and USB drives.
