Never seen Ranish; it's a non-destructive partition manager, right? I've seen some, but they seemed pointless - they basically would wipe the drive, then re-partition it - you can do that in Windows anyway. I'll keep that page bookmarked though, in case I get a chance again to try something like that out.
I've recently purchased some stuff from Acronis - TrueImage and DiskDirector. TrueImage seems a darn bit better than Norton Ghost - lots more nice features, such as a utility that directly creates a bootable imaging CD. I think Ghost (2003 version anyway) only did bootable floppies. And it imaged both of my hard drives without any issues at all; very easy to use.
