Just boot up knoppix, mount root partition that contains dcfldd, go to wherever the executable is located (e.g. /usr/bin/dcfldd): 1. boot up knoppix 2. create a partition: mkdir /work 3. mount /work to the root partition: mount /dev/sdc /work 4. cd /work/usr/bin 5. run dcfldd: ./dcfldd If your root partition is encrypted (e.g. mine is), then place a copy of dcfldd on the boot partition; no boot partition, put a copy on its own dedicated little partition. Of course, you can always put a copy on a USB jumpdrive. As a last alternative, download and compile a copy while in knoppix. > Or is there a way to do such copies from a one disk to another while > one disk is booted??? Sure, but the running disk/sector would have temporary files that would not consistently hash when you did the hash check. If you do this, try it in linux without bringing up X. This might avoid copying some software "locks" that could block startup on the copied disk/sector. HTH
