Been talked about over and over again, you could search through the forums and find a lot of information. No sense in witing too much in this post, particularly since we don't know anything about your equipment (do you have a local network you could transfer files to? Would your configuration let you write files to CD or DVD? Do you have a USB flash drive or other removable media? How much space do the files that you want to recover take? and so on). Can Knoppix even see the files if you boot it from CD? (Don't give up if it can't, all is not lost yet, but it would be nice to know). And whatever you do do not write to an NTFS partition with Knoppix while you are doing this.
