Hello Everyone.
I ran into what I think is a big problem. Last night I could not access the files on my DNS-323 anymore. So I logged into the web interface to see if I could find anything wrong. As soon as I logged in, it is asking me to select my RAID level. If I choose any of the levels, it then alerts me that the drives will be formatted which I don't want to do. Is there anything I can do to get my RAID array back?
I am running RAID 1 with 2 160GB hard drives with the latest firmware on my DNS-323. Also when I was looking through my e-mails, it appeared that I got an alert on January 16th saying that 1 of the drives had failed.
Any suggestions would be helpful. Even if I could just access to drives to pull the data off them that would help out a lot.
Thanks in advance!

You can try putting one of the drives (or both, one by one) in another computer running either linux or Windows with the ext2ifs installable file system driver.

Just put in another drive of the same size and have the raid rebuild
-
If only one drive was bad, the data would still be available, so this probably isn't going to work.

He said one of his drives failed, why cant you just replace the bad drive and rebuild the array isnt that what its supposed to do ?

Even if one drive failed, the second should still be available without rebuilding. Mounting the drive on a linux box is probably the safest method to try accessing the data.

Thanks for the replies guys.
I tried hooking up both the drives to a Ubuntu system and I was not able to see the data, I can see the partitions but can't access them. The only partition that I can access on either drive is a 523mb partition called backup, which contains no data.
I have also tried installing just one drive at a time on the NAS, when i try to access the NAS with only 1 drive, I cannot see any volumes, just the shared printer and webpage volume.
I also tried inserting a new drive of the same size along with one of the old drives and went through the steps of rebuilding the array, although at the end it came up with a new name called Volume_2. After this completed I still could not see Volume_1 or 2 through the network share.
I'm afraid to try anything else as I don't want to lose the data that was on the drives(although I feel like it has already vanished).
Any other suggestions? Or free third party software I could use to recover the data?
Thanks in advance

Is it safe to assume you know enough about Unbuntu & linux to properly mount the drives and access them? Personally, I don't, but ext2ifs has worked for me.

The drive will not get automounted by ubuntu because the partition is flagged as linux_raid.
You should mount it manually with something like 'mount -t ext2 -o ro /dev/sd?? /media/usb'

I wasn't able to mount the filesystem from either drive. Both drives lost their file table. I tried just about everything and every piece of software. Even forensic software. Finally I came across a piece of software from a company called Nucleus Data Recovery. Their software is called Kernel Linux Data Recovery Software. Worked like a charm, I recovered nearly every file including the file names and directory structure. Best $50 I ever spent. I'd recommend it for anyone in my situation.
Thanks for your help on this matter guys.
