Hey,
I just installed Knoppix v3.9, because my Windows XP was not working correctly (problem with the SOFTWARE register file).

It installed successfully, and my main goal is to backup the data on the internal laptop harddisk.
When I click on either of the two partitions of the HD, it says "mounting" and a bar with a percentage sign. I clicked the X here, because I didn't know what it was doing. What is this prossess doing?

I also got a USB harddisk connected, and I could access that one without doing the mounting thingy.

Can anyone explain what this feature does?
