I am trying to recover some files off a failed Fedora 12 install. When I run Knoppix 6.2 the only partition I see is /boot. I have 2 40Gb IDE drives: +++++++++++ root@Microknoppix:/home/knoppix# fdisk -l Disk /dev/sda: 40.0 GB, 40020664320 bytes 255 heads, 63 sectors/track, 4865 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x000f053e Device Boot Start End Blocks Id System /dev/sda1 * 1 25 200781 83 Linux /dev/sda2 26 4865 38877300 8e Linux LVM Disk /dev/sdb: 40.0 GB, 40020664320 bytes 255 heads, 63 sectors/track, 4865 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x73b073b0 Device Boot Start End Blocks Id System /dev/sdb1 * 1 4865 39078081 8e Linux LVM Disk /dev/sdc: 2004 MB, 2004877312 bytes 16 heads, 32 sectors/track, 7648 cylinders Units = cylinders of 512 * 512 = 262144 bytes Disk identifier: 0x2d95de6b Device Boot Start End Blocks Id System /dev/sdc1 16 7648 1953856 e W95 FAT16 (LBA) root@Microknoppix:/home/knoppix# ++++++++++++ I have tried using the commands found in Hack #75 Knoppix Hacks and got the following error. +++++++++++++ root@Microknoppix:/home/knoppix# sudo mdadm --assemble --auto=yes /dev/md0 /dev/sdb1 /dev/sdc1 /dev/sda1 mdadm: cannot open device /dev/sdb1: Device or resource busy mdadm: /dev/sdb1 has no superblock - assembly aborted root@Microknoppix:/home/knoppix# sudo mdadm --assemble --auto=yes /dev/md0 /dev/sdb1 /dev/sdc1 mdadm: cannot open device /dev/sdb1: Device or resource busy mdadm: /dev/sdb1 has no superblock - assembly aborted +++++++++++++ Any help would be greatly appreciated.

Can you try this in Knoppix? Code: modprobe md modprobe linear modprobe multipath modprobe raid0 modprobe raid1 modprobe raid5 modprobe raid6 modprobe raid10 cp /etc/mdadm/mdadm.conf /etc/mdadm/mdadm.conf_orig mdadm --examine --scan >> /etc/mdadm/mdadm.conf mdadm -A --scan What's in /etc/mdadm/mdadm.conf?

Ok, there are no RAID arrays on your system. Can you run Code: /etc/init.d/lvm start in Knoppix and then post the output of Code: lvdisplay ?
Problem Solved Hi Falko, Thanks so much for your help. Not certain why I got it in my mind that I had a Raid 0 setup. I am now able to get the files I wanted to save before I did a full install of Fedora 12. Below are the results of the commands you asked me to run.
