Most HD mfr's provide something similar as a free download - check your drive mfr's sites. Or check at MajorGeeks.com and search their site on Disk Imaging. Otherwise, you should be able to get your hands on a copy of Norton's Ghost very inexpensively. Just use the price search engines - a copy of the 2004 version of SystemWorks Pro is the holy grail. It includes SystemWorks and Ghost and other stuff. Otherwise, if it's the best you want, just pop for a copy of Acronis True Image.
