I got Paragon Partition Manager and Paragon Copy for free on a PC magazine disc... both are quite useful tools, though I've since replaced them with Acronis True Image 2009, which these days (along with Windows Disc Manager) takes care of all my disc management and backup needs.
For those who cannot afford Acronis, there are free backup and disc management tools from Easeus... here and here
As noted by Karen, Easeus's Partition Manager is 32 bit only, but their Todo Backup and Disc Copy operates on both 32 and 64 bit systems... and both are freeware.
My sister uses Easeus Todo Backup with an external drive and has been quite happy with it, having saved her from lost data and needing to reinstall everything after a system crash, ect. Much like Acronis True Copy Easeus Todo Backup will create a copy of your entire system (installed programs/files included) and completely restore it in the event of a crash/need for a system rewrite.
