help needed - broken raid 1 array - I think I messed up

[anon20120409 <anon20120409@gmail.com>]

Hello everyone,
I am not sure if I am using this mailing list correctly, but I have a 
big problem with my raid setup. So if anyone is interested, please help...

I have a raid1 setup with 2 hdd. One day I saw in the SMART data of one 
on the disks that it had some bad sectors, so I thought I must replace 
that disk before it is too late. Following are the trial and error steps 
that I took and messed up the situation...

While the pc was off, I diconected the hdd with the bad sectors and 
place in the same port a new disk (same model and brand).

I entered the Matrix Raid system and as I remember it said something 
like "One of you disks needs to be rebuilt, do you want to do this?" and 
of course I presses yes.

I tried to boot into ubuntu, but the drive was not mounted.

So I thought I must sync the disks. I tried to mdadm --assemble --force, 
but the disks were in use by dmraid (which I didnt know that existed), 
so no results. I also tried different mdadm commands (--scan, --create, 
--examine), but I think nothing happened as the disks were busy by the 
dmraid.

After, I plug all 3 disks and reboot. Probably bad idea.

I reboot with only the 2 old disks pluged.

and at this point I think that the old disk without bad sectors synced 
from the blank new disk and I lost everything, but I am not sure.

Any help is very appreciated...

Thanks in advance!
