Is my Duo v1 dead?

Many thanks to both of you for replying.

StephenB, I will try your suggestion over the weekend if I get a chance - I'd like to secure another backup before blowing up what at the moment is my only good copy with all the files in 1 place. I do have everything secure, but it would take a bit of effort to put it all back together.

mdgm, as your suggestions only take a few seconds to run, here is what I found;

# sh /bin/start_raid.sh
# echo $?

# cat /proc/xraid/configuration

Now if I read that correctly, it's saying I have 2 drives (both "present"), 1 of which is faulty? Physical drive 0 (can I assume disk 1) is the faulty one? If this is correct - it doesn't make sense - disk 1 is the one I can read the files from through Ubuntu.

My need to check disk 2 and copy everything to it outside of the Duo just increased!!
