How to copy a hard drive?

I bought a new 160GB hard drive (thanks to bs16yg) to replace my old 40GB hard drive. I don't want to reinstall Windows and all other softwares in my new hard drive. Rather, I would like to copy my entire old drive to my new hard drive. I know people call that "ghost". But I don't have software to "ghost" it. Is it possible to just copy everything from old drive to new drive and then use new drive as master drive?

Your advice and experience will be greatly appreciated.
