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.

       dmesg | tail  or so

root@archive:~# dmraid -ay

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!
