That's where EaseUs Disk Copy comes in handy. This free tool comes as a bootable CD so it works regardless of the operating system you have installed. The downside? It comes packaged as a Windows executable.

- Select the source hard disk.
- Select the destination hard disk.
- Confirm, then wait while the disk cloning is progressing.
During source and destination disk selection, you even get to view of the partitions on the selected hard disk (but not the contents) to help you decide which is the correct hard disk.
That's about it. Simple.
