One of my partition is not present

[b4you-bbog]

I've just tried Knoppix and I have noticed that one of my five partitions is missing. I don't know almost anything about linux and my firs impression was very good. The first partition is labelled with something like “hard disk 1”, ”hard disk 2”, “hard disk 4”,”hard disk 5”, “hard disk 6” and the “hard disk 3” is missing (I think this is my partition with my music). Why knoppix does not see all my partitions? Pls help!

hmm we need some help from you to see what is wrong, likely it is NOT missing but is just a extended partition with the rest under it.
if you open a console (screenlike icon at bottom of screen) and type

sudo fdisk -l

and hit enter what does that output? what does the comand mount say?

mount

what does dmesg say about your disks?

dmesg|grep hd
