Is MyCloud Drive corrupted? (400044 error)

You will need to move up to the top root directory. Try performing the following command: cd ..

Then perform a directory listing.

I would use cd / cd … will put you in the /home directory.

Alright I’ve got into the main folder, but shares is red and points to DataVolume. I think red means it’s an archive, but I can’t access it. If I do a cd /shares, it says it doesn’t exist. If I go into DataVolume, it says it’s not there either.

According to another post, they found the .WDsync within the mnt folder, but my mnt folder has nothing in it.

My temp folder also has very little in it.


It kind of ■■■■■ that it won’t behave like a normal drive so I can’t just hook it up to the computer and view it through a normal browser.

I think I see your problem.

/shares is pointing at a non-existing location. (/DataVolume/shares)

When you tried to enter /DataVolume/shares, you used dd, not cd. VERY VERY different command. Dont play with dd unless you know exactly what you are doing. :stuck_out_tongue:

Try the following:

cd /DataVolume


This looks different from my Gen2. Is this a Gen1? Regardless, it thinks the /shares symlink is broken, which means there is no /DataVolume/shares folder.

The output of the commands I suggested above will help diagnose this issue.

Try a du -h -d 1 from the / directory. This will tell you which each folder contains. You
then may try hat command from the /dataVolume.

You can hook the internal hard drive of the My Cloud up to a computer running Linux (or a Linux plug in for Windows) and view the contents of the hard drive.

There are other programs like WinSCP ( that can be used to view the contents of the My Cloud (via SSH) which behave similar to using a file manager. That will alleviate the need to know various Linux command line codes to navigate the directory structure of the My Cloud.

Here is what I got when I ran those two commands. I first accidentally tried to run them simultaneously. xD


I see no shares folder. I added -h so I could see file sizes in more general measurements and these sizes don’t look that crazy, yet the drive is still full.

I ran df -h in the main folder and didn’t get results that were much different.


OH WOW this is VERY useful!! I suppose as a last ditch effort (when I get the drive working) I can send files this way… at least from the same network. It also even now gives me a better idea of what’s going on now. Using both this and the command line is quite useful. I’m still having the issue, but this is very helpful!

can you give me the output of

ls /dev | grep sda


dmesg | grep sda



I suspect that your data volume is not getting mounted. This LOOKS like a Gen1. If my memory serves me right, the proper partition would be /dev/sda4. It is not mounted when viewed with df.

Sure. Just to be clear, I’m doing this from the main folder right?

Here is the first one you requested.


Second request

Final request

Let me know if that helps.

If you look at the second request. YOu will see that the sda4 partition has problems.
You need to run fsck on the sda4 partition.

Do I just do a “fsdk sda4”? What is the specific command for that? Thanks.

The command is:
fsck /dev/sda4

I’ve ran the check with this as the results. It looks like it’s not done yet though.


It can take awhile. There are several passes.

Alright, sorry for the delay. Here is the finished check.

It asked if I wanted to fix a few things. I said yes as you can see.

As an aside, I looked on the drive and NOW the light is red. It’s been blue up until now. It’s almost like it didn’t even realize it was broken.

Time to reboot. Lets see if it works.

Thanks! It is working now… for the most part. Now I have the common problem of WDSync taking up a ton of space…

But when I try to go in and check the folder, it tells me that the folder doesn’t exist even though it shows up in the list.


I can add things to the drive again though so that’s good.

You are currently in the DataVolume/shares folder. You just need to cd WDSync
You could also do a du -hd 1 This will show how much disk space each folder is using.

Ah okay thanks. It listed a few of the folders, but I assume it is still looking as it put the curser to the beginning of the next line, but without the WDMyCloud:/#.

I did a du -h on a folder above and there’s something in one of the folders (either DataVolume or CacheVolume that is taking up 3.2TB and I have a strong feeling it’s in my WDSync History/Changed and /Deleted folders within one of the share folders, but trying to get to it on Windows causes the explorer to freeze. Possibly due to so much space being taken up.
