Recuperate data from hdd

[armando]

I had ubuntu in my computer. Recently it colapse.

I installed Knoppix to try recuperate the data , but the partions are not shown in the desktop. Why? I dont know.
I can not mount the partitions due to this problems.

Can I create a new partition on the colapsed hhd to install Knoppix there?

In step than run cd live Knoppix? Copy in a new partition along side the Ubuntu OS,
can any body pls comments.

Regards
