Hi all
Owen can go home tonight knowing that it all is working fine for me and thanks for
enabling me to get access to the data I needed.

No probs. I just rebooted the host machine I'm copying this stuff onto and when it
came up again I did a "/sbin/mdadm --examine /dev/sdc5" and now it shows all the
details for it like before.
So I did your
# /sbin/mdadm --assemble /dev/md0 --run -u
b6035660:c11a8a2e:7026aea2:99d23bfc /dev/sdc5
and then mounted it OK.
So now I'm copying stuff off this partition fine.
I have copied the stuff off partition 1 OK too.

No recognisable superblock on /dev/sdc5
dev/sdc5 has wrong uuid
No devices found for /dev/md0
BUT! I tried it with sdc1 using it's uuid and it works!
I message came up that /dev/md0 has been started with 1 drive out of 2
Then mount /dev/md0 /mnt worked and I can see the files and directories.
I can now see the old /etc/fstab and it tells me that it was a reiserfs
system.
What I don't follow is that now If I run:
/sbin/mdadm --examine /dev/sdc5
"No md superblock detected on /dev/sdc5" where as before it said
/dev/sdc5:
Magic : a92b4efc
etc....
I have some playing to do to work it out but am now much relived I can see
data.
Hope it works out ok...
cheers,
Owen.
N.B. Read the man pages, check the syntax, only then then run commands
as root on data you're trying to recover...
