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

[Dazed_75]

Knoppix may be using the swap partition on your hard drive.  If that is
included in the image created using dd, the md5sum will certainly change.

In addition, Knoppix CAN be set up to save various information in a file on
persistent storage so as to retain same between live boots.  While I doubt
you have done this and so it should not be the reason for your situation, it
seemed appropriate to point this out.
