DriveimageXML is free, the others afaik aren't. You could also try
gparted or clonezilla live cds.

And if you already have a Windows XP installation CD try ubcd4win
http://www.ubcd4win.com/index.htm - it enables you to create a bootable
minimal XP CDROM which also includes lots or useful repair tools, including
a password resetter and DriveimageXML.

Windows won't let you restore an image over itself while it's running but
when you're running from the CD you have full unrestricted access to your C
drive.
