HELP with lost data from Netgear NAS DUO

[ITS]

Hi to everyone.
I am in very desperate situation. One of my NAS drive, running 2x WD 1.5T has stop being recognized in the network. The Radar soft detects it only at the beginning of the boot up, showing checking file system and after that the NAS disappears. I took out the hard drives and connect them to Ubuntu running machine: one of them shows SMART error and can't be mounted in Linux, the other shows NOTHING, thought that bought hard drives ware mirrored in the XRAID format.
Is there someone experienced similar issues and having any solutions to help me in this.

Hi.

I think you need to be more descriptive of the things you've already attempted. Details about the kind of tools you used (for querying SMART or mounting), what kind of filesystem is supposed to be present and some info about the partition table.

Hi,
the file system Linux Ext2/Ext3. This is what according to the Ready NAs duo specification is.
I tried to access one of the drives using this:
CODE: SELECT ALL
sudo apt-get install mdadm lvm2
sudo mdadm --assemble --scan
sudo modprobe dm-mod
sudo vgscan
sudo vgchange -ay c
sudo mkdir /readynas
sudo mount -o ro,user /dev/c/c /readynas
sudo ls -al /readynas/home/admin/

but unfortunately I couldn't manage to mount the drive.
The SMART error is on one of the hard drives> As soon as I plug it in at Linux computer it shows SMART error.
The other hard drive shows unknown file system, thought it was supposed to be a mirror of the first one.

Thanks.

How much disk space did the NAS provide before it failed this may give us a clue to the raid config either RAID0 striped or Raid1 mirrored if it was 3TB then it was RAID0 which is very common for these NAS setups if that is the case you need both drives to re-create the raid0 set however one of the drives is showing bad due to the smart errors.
