NAS died, any way to get the files out?

I'm not that savvy when it comes to hardware and this is the only tech forum I know, so if you need me to provide more details I'll gladly do it, just let me know what info would be helpful...

long story short, I had a Zyxel NSA 320 (http://www.amazon.com/NSA320-Perf...B004UBU3SY) which died.

I had two drives in it configured as JBOD, and I'm wondering if there's any simple way to mount these drives separately to get the data out.

I plugged one of them into an HDD dock and it shows up in the disk manager (see attachment), but I can't seem to find any way to get into it or have it show up in explorer.

this isn't unexpected, since I figured that they're different file systems or something...

but the fact that I can see it and it says "Healthy Partition" makes me hopeful that perhaps I can somehow open it up and recover some of the files and/or directories.

can it be done? do I need specialized hardware or a different OS, perhaps a Live CD that can read a different file system that will let me mount the disk?

Sad part of this is that it died while my replacement NAS was in the mail which I was going to use to backup everything on this one :/

anyway, if anyone can provide any insight, even if the answer is no at least I can reformat the drive without feeling bad that I could have recovered some of it...

thanks!

Odds are the old nas was running some sort of *nix flavor so the drive is probably formatted ext2/3. Try booting from a live fedora or Ubuntu disk, it should mount right away and you can transfer files to your new nas.

If the only thing that died was the enclosure's guts, all of your stuff should be there and readable.

Give it a shot with a Linux live CD. Maybe it was formatted as ext (2,3, or 4). There are a ton of them available, but Ubuntu is usually a safe bet: http://www.ubuntu.com/download/de...ou-install

thanks for the quick replies! I did manage to boot with a live cd i think it even was ubuntu, but wasn't sure what to do once i got in...

what besides booting and connecting the drive would i have to do to see it? does it matter that they were two drives joined as JBOD but I only have one dock?

if anyone can point me to a beginner type resource that can help get me familiar with working with disks in ubuntu that would be helpful.

either way I'll try again and see if perhaps I can post more screenshots if that might help.

thanks again for taking the time to help

Generally I would expect the drive to be mounted automatically and show up on your desktop, but it's possible if it's a linux native partition ubuntu assumes that it will be mounted using traditional means.

Something very close to the partition manager in windows in Linux is called gparted. It should be on the live disc you burned. I don't have a good howto handy, but the documentation is here: http://gparted.sourceforge.net/

If the partition is of type ext2, ext3, or ext4, try mounting it somewhere on the system. Instead of using drive letters, linux mounts drives to folders in your existing filesystem. You can mount drives through gparted, or using the command utility 'mount' (man mount for usage).

Alternatively, you could try installing ext filesystem software for windows. http://www.ext2fsd.com/ is one I've used before.

I'll have to check when I get to work, but I recently had a Readynas Ultra2 "die" on me - wound up being one of the drives toasting, but I found a recovery program that would read the drive just like a regular file system in Win7 and recover the files, even with one dead drive.

if you did use Ubuntu, click on the unity button (very top on left hand dock) and type in gparted. it is just like the windows partition manager. Then select the drive from the drop down and see if it can tell what type it is.

i'm not entirely convined it was just the nas that died (the fan stopped turning at the same time it stopped working, but one of the drives is emmitting intermittent clicks Frown )

but do you recall the program you used by chance?

thanks for the tip on the extfsd that was very useful, unfortunately it's not ex2, it's showing RAW for the large space I expected the files to be (attached)

am I out of luck?

From the manual:
Quote :
3. What is the file system supported in NSA320? Internal file system: XFS (or EXT4).
Check if the Ubuntu live disk has the xfs module loaded. You might need to install it. If it doesn't recognize xfs it might interpret it as raw.

Reclaime

Basically I just googled on how to get data off the failed device and found a youtube video of that program. The one you can dl for free is somewhat handicapped but after connecting the drives I could browse to any directory. I have yet to actually try a full recovery due to disk space limitations but I am trying today,.
