How do I save a disk image of my laptop hard drive?

[Mark Phillips]

Well, what a pickle I have created!

I believe this method works, except I can't get md5sum to generate a reliable 
checksum for the hda drive on my laptop. I thought knoppix didn't touch the 
local drive, but each time I run 

md5sum /dev/hda

I get a different result. I assume the hard drive is changing somehow, even 
though I am running knoppix off the cdrom, and knoppix says it is not 
mounted.

So, I will look for another way to do this. Sigh.
