Hard drive mirroring/backup software?

[flashbacck]

Hey,
My harddrive's been clicking like mad, so I'm planning to RMA it. But, of course, I want to backup everything before I erase the drive and return it. Is there any software I can use to backup my harddrive onto CD-R's? Then when I get the replacement HD, I just bootup with the CDs and they unpack everything back onto the HD?
Thanks

EDIT: nevermind! I found another thread someone made about harddrive copying, and I think someone mentioned a backup until that can backup to CDs
