Yes, I know.  I did that at the time when I still needed dual-boot.

No, what I want is more generic (and it is slightly offtopic since it is not 
specifically meant to tryout malware).
Suppose I visit a friend who has a botched system, and I carry with me my 
linux laptop and a knoppix CD.  Now if there would be a way to backup his 
entire HDD with just the tools on the CD (and the laptop as receiving host) 
that would be fantastic. 

I was thinking of something like using {tar | dd | cpio} and netcat but I'm 
unsure if it can be done, much less how to proceed.

This works just fine for one or two drawbacks: You need to plan this in 
advance, and malicious code that randomly overwrites disks will kill linux + 
imagefile then, too.
