Continued fooling around with it. Finally did a mkdir h** in /media and was able to mount -arw hdc on h**. This still did not let me save a leafpad file to h**/** (error can not open file). Saved to Desktop and then used the xterm to cp from Desktop to the hdc/** file I wanted. PITA but it worked. I think that Knoppix 6.0.x needs some work.
