Knoppix Hacks - Trying to see my Raid drives

Hi,

I am using Knoppix v6.2 to recover some file off my Fedora 12 box. The install of the Fedora 12 upgrade went bad.

I have a copy of Knoppix Hacks and on page 226 (Hack #75) Kyle describes mounting a Raid drive. When I use the mdadm command as described I get a error message “No such file or directory”. See results below.

#####
knoppix@Microknoppix:~$ fdisk /dev/sda

The number of cylinders for this disk is set to 4865.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p

Disk /dev/sda: 40.0 GB, 40020664320 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Thanks for your time,

For clarification I have 2 40Gb IDE hard drives in my Fedora box. When I boot Knoppix it only sees /media/sda1 my old boot partition.
