Yes you can back out without losing your data.  I can give you the instructions, or a script that I have written to do it automatically.

A few things first.

1) You will need ffp installed.  I'm using 0.5.  It can be removed after if you don't want it.
2) Was your RAID set-up with F/W 1.05?  If not, what version?
3) Does your web admin access work correctly (no errors about swaping drives or wanting to reformat)?
4) Is all your space set-up for RAID1, or do you have JBOD at the end of the disk?

Does not always work with 1.05.  Since it does not zero the superblocks, sometimes when rebooting the unit, it will pick the array back up in a degraded status, then drop it again, etc.

find ffp here: http://dns323.kood.org/howto:ffp

You will also need putty or another telnet program on your computer.  http://www.chiark.greenend.org.uk/~sgta … nload.html

I will attach the script.  Currently I have not written the safeguards into it that I want to, but I have been testing this for several weeks (both breaking and creating RAIDs) and have not lost any data, regardless of what has gone wrong.  (Just so you know, the safeguards are against having the wrong F/W or not having the drives set-up correctly in the first place -- they do not apply to your situation.)

You will need to follow instructions exactly.

1) Copy the attached script file to the root of your DNS's hard drive (usually Volume_1)
2) Install ffp (give the unit around 5 minutes after installing it to allow it to be fully synced)
3) After you get the ffp installed (instructions on its page) will need to telnet in.  Using putty is easy, just enter the address of the dns and make sure telnet is selected.
4) Once you have established the telnet session type: (you will not type the "/ #" that will already be on your screen)

 / # /mnt/HD_a2/break_raid.sh

5) After that runs, there will be a line of instructions.  I will also put them here: (lines 6-12)
6) Type exit and hit enter; the telnet window will disappear.
7) Go to the web admin tool and shutdown the unit.
8) Eject drive 1 (left bay)
9) Start the unit up.
10) Shortly after all the lights stop blinking, you can telnet back in again.
11) Push in drive 1 (yes with power on).
12) once all the lights stop flashing type:

/ # /mnt/HD_a2/break2.sh

13) Unit will automatically reboot and you are good to go with 2 drives with all your data on each.  (If you forget to push the drive in, you will get a message reminding you.

Ask if you have any questions or worries BEFORE you try things.

As alway, I do recommend a backup of data, but that is your choice.

NOTE: THIS IS FOR F/W 1.04 or 1.05 ONLY!!

What are the results? Did it worked? I'm about to do the exact same procedure. Please let me know if it really worked...

If the disk was empty at that point, you did something wrong.  The reason that the web admin tool is saying it wants to format and setup the array is because the configuration files are not correct in one or more of the following locations: disk 1, disk 2, flash block 0, flash block 1.
