Can't find testdisc on Knoppix - is it there?

Hi all

I'm trying to repair a corrupted parttition table on an Ubuntu distro laptop. I've downloaded version Knoppix V5.1.1 as instructed at various websites so as to use testdisc to repair the partitions.

However, I can't find testdisc on the Live CD. It booted up off the iso file nicely and knoppix is working fine - How or where do I find testdisc? According to the testdisc website, it is on the Knoppix cd

Thanks

Do you mean testdisk?
