Knoppix and SCO Unix

I booted Knoppix on our SCO Unix computer. It worked fine - except it couldn't mount the SCO disk. Is there a filesystem available to do that (I think SCO uses something unusual. S51K or something like that?) and how do I get it? Is it safe? Thanks. I know computers, but less about Unix/Linux than others.

I saw this post on another site. Not sure if it helps, but I am dealing with the same issue. Trying to get data off a SCO disk. http://codeverge.com/grc.techtalk.li...nd-sco/1591364
