If all you want to do is a one-time clone of a hard drive (such as to install a new larger primary hard drive while keeping everything on your old drive), then download the 14-day fully functional trial copy of Acronis True Image 9.0 at www.acronis.com. You'll be able to make your image for free - I did exactly that. But once you've downloaded it, see how easy it is to set it up to make regular automatic images so you can restore from any hard drive crashes without any lost data and no need to reinstall Windows or any programs. True Image just saved my butt - I installed it three weeks ago and had it making weekly full images and daily incremental images, automatically. My timing couldn't have been better. Last week, my Windows got corrupted and wouldn't boot - I restored the prior image using the Acronis boot disk, and I'm back to normal again with no problem, and no need to reinstall Windows or all my programs (let alone no lost personal files). It's a great, user-friendly program, and you can easily find it for less than half the price of Norton Ghost, which I understand is not as friendly for non-technically oriented people and does not have some of the features Acronis has. Among other things, Acronis handles both disk imaging and individual file backup, and can restore individual files from an image.
Before finding Acronis, I bought VCom Copy Commander, because it was cheap - about $30 compared to about $70 for Norton Ghost. It might work for a single clone, but does not have the automatic scheduling capabilities of Acronis, and does not run within Windows (runs on Windows systems, just not while Windows is booted). I regret that purchase. For the same price, I got True Image 9.0 at Newegg.com (downloadable version). Definitely worth the money. Make sure you get version 9.0 if you purchase -- for some reason 8.0 is more prevalent (sometimes, oddly, for a higher price than 9.0), but 9.0 is more feature-laden. (And don't buy it directly from Acronis, as it is $20 more there.)
No connection to Acronis and no axes to grind against Norton or VCom - just appreciate that this program was reasonably priced, easy to set up, and worked exactly as advertised.
