Which software for Imaging Hard Drives?

[Confused_Chimp]

I'm looking for some suggestions for ideally freeware opensource packages that are very good at taking a image of a hard drive or backing up a hard drive so it can be 'ghosted' back later, without having to reinstall etc.

Any suggestions?
Many thanks
