How to Recover Data From a WD — My Cloud 2TB External Hard Drive (NAS)

Disclaimer: I am not responsible for any issues that may occur as a result of following this guide. If you have any concerns about what you’re doing, please stop and do your own research.

I purchased this product sometime around September 23, 2016.
My Warranty expired January 18, 2017.

After a surprise power outage, I was unable to access my data on my share drive. When I logged into the My Cloud device to troubleshoot, I saw this error message:

Volume Failure
The data volume 1 on the drive is not accessible. Contact WD Support.

Product: WD My Cloud 2 TB
Brand: Western Digital
Model Number: WDBCTL0020HWT-NESN

Prerequisites

Please ensure you know the IP Address or Hostname of your Western Digital My Cloud 2TB Network-attached storage (NAS), you will need it later on. You should also have basic familiarity with a Linux command line.

You’ll also want to download and install WinSCP: https://winscp.net/eng/download.php
or get it from the Microsoft Store: https://www.microsoft.com/store/apps/9p0pq8b65n8x?cid=downloads

Optional Tools: PuTTY: https://www.putty.org/

Begin

First, we need to turn on the SSH service on the WD My Cloud device.

Navigate to your WD My Cloud web page and go to Settings > Network > Switch SSH to ON. (Don’t click Configure. Doing so will prompt you to change the SSH password. We don’t need to do that.)

Login to your My Cloud.
Switch SSH to ON.

Connecting to our drive via WinSCP

Next, open WinSCP (You should have installed this earlier.)

Open a new session, set these options, and click Login:

  • File Protocol: SCP (SCP means Secure Copy Protocol)
  • Host Name: IP Address or Hostname of your WD My Cloud device. (It’s the same IP Address or Hostname that used to login to your My Cloud earlier.)
  • Port Number: 22 (Default Port for SSH and SCP is 22. Leave this alone.)
  • User name: sshd (The Default username for all WD My Cloud devices is sshd. If sshd is incorrect, try root.)
  • Password: Your password that you use to login to your WD My Cloud.(If your password isn’t working, try welc0me. This default password is just the word welcome with the Letter “O” replaced with the number Zero.)
  • Click Login!

If you are prompted with “Continue connecting to an unknown server and add its host key to a cache?”, press Yes.

Continue connecting to an unknown server and add its host key to a cache? press Yes.

If you successfully login, you will placed in the File Directory: /home/root

Using the file browser controls, move to the File Directory: /mnt/HD/HD_a2
(This was the file directory path for my data, it could differ for every device.)

Next, copy/paste your data to your computer or a new storage device. This copy process could take several hours, so I suggest leaving your computer on overnight. It took me about 4 hours to copy 80 GBs. I’m sure 2TB (2000GBs) of data would take much, much longer.
