You may still be able to access your hard disks with Knoppix. After booting Knoppix you first must load the md driver & raid drivers: `modprobe raid5` should do it. Then, use the mdadm command to query the raid information written to the hard drives, i.e., `mdadm --detail /dev/sdx`. Once you think you have the right configuration start your raid array with `mdadm -A /dev/mdx /dev/sdy ...`. Finally, once your raid array is up & running you can bring up lvm. Again, learn your configuration with pvdisplay, vgdisplay & lvdisplay. Then, make your logical volumes active with `lvchange -ay vgx/lvx ...` Once your logical volumes are active you can mount them, i.e., `mount -t ext3 /dev/vg0/lv_root /mnt`. Of course, use whatever details are appropriate for your system.
