Mirror Orphan Repair on 2200 gone wrong. Help Please

Hello

I got a 2200 snap appliance back and one of the drives sounded very unhealthy so I decided to just go ahead and change it after finding the following two links:

http://wiki.procooling.com/index.php...air_for_Orphan
http://ezinearticles.com/?Hacking-a-...rive&id=151888

Now I followed the directions in the second link more as it replicated exactly what I had: A broken mirror and one good drive.

I couldn't find a way to backup the data as the snap was set as part of a domain and I didn't want to change it to workgroup as it would lose the permissions. The FTP server didn't work very well either and I wasn't about to download 110+Gb, 1 file at a time. I also didn't have another FAT drive with 120 GB free to do the DD backup. So I thought I would triple check everything.

Without referring to the webpages, here is what I did as I took notes at every step.

1 - Put my good drive in the top bay
2 - Put my new drive in the bottom bay and made sure it was set to master
3 - Rebooted the server and logged into the webconsole and it said it was formatting the new drive and the good drive was showing as missing the 2nd drive of the mirror. So far so good.
4 - I then ran "co de format 10010 /reinit" without the quotes from the debug page
5 - Restarted the snap and waited for it to finish the format of the new drive
6 - I couldn't find a diamondmax10 so we ordered a diamondmax20 160GB which had all other specs similar to the current drive. But I noticed the total size on the new drive was about 2 -3 MB less than the good drive. So I thought I better do the next step of breaking the mirror.
7 - I ran the command "co de config individual 10000 10010" from the debug and restarted
8 - After restart, I had 2 single drives. In the webpanel disk status page, the good drive showed at the bottom and the new drive at the top (though physically they were the other way around). So I thought this looked normal.
9 - I triple checked and compared the above 2 links and then ran the following command "co de config mirror 10000 10010" and rebooted.

At this stage I expected the good drive to mirror its data to the new drive. Instead, after the complete of the mirror, Lo & behold, all the data was gone


So now you know the history, I have a few questions please.

1 - What did I do wrong?
2 - The drive I am replacing is still a bit usable and has all the data on it
a) How do I backup the data to another drive, preferrably to NAS storage over the network?
b) Will taking a Ghost image be good enough to restore stuff onto the original good drive?
3) If the above 2 methods aren't possible for data backup, is it possible to connect to the snap using UNC without changing the snap from being on a domain?
4) Lets say I have 120Gb of files on the current drive, do I need 120Gb of free space to put the image on created by DD? (I think I know the answer to this, I just need to confirm).

Thanks in advance for any help you can offer.
