[GUIDE] How To Unbrick your 2TB/3TB/4TB My Cloud


#1

I'm not great at guides.  Alot of people in these forums helped contribute to what I'm writing, here.  I thought it best we have a central simplistic guide towards recovering our devices in the event of catastrophe.

BIG credits and thanks go to  cnlinya for her work in the beginning of 2014,  nfodiz for his MyBook Live guide, and resize fix, and  WSGVET for his virgin 2TB My Cloud image.  None of this was possible without their input.

Standard disclaimer:  You void your warranty by doing anything in this post.  I (and the above named) are not responsible if you lose your data, bork your drive, or otherwise cause the end of your universe.  Back up your data.  Give to the homeless.  Hug a stranger.  

It should be mentioned, this guide is a LAST RESORT to repair your My Cloud.  _ THESE STEPS WILL RESULT IN THE LOSS OF ALL USER DATA.  YOU HAVE BEEN WARNED. _

_   _

Needed stuff to download:

  1. WSGVET's Virgin 2TB My Cloud Image
  2. SystemRescueCD

Needed hardware:

  1. 8GB+ USB Drive (formatted NTFS)
  2. Blank CD/Burner
  3. Credit Card, or slim-tip screwdriver
  4. Philips Head Screwdriver
  5. PC with SATA connections (You can try SATA->USB converters, but I won't get into them here)

 

What To Do

 

  1. Burn the SystemRescueCD.
  2. Unzip the Virgin Image, and copy the mycloud2tb.img file to the USB Drive.
  3. Disassemble your My Cloud.
  4. Pop the CD, the USB Drive, and the WD Hard Drive into the PC. (It is recommended you disconnect any other drives, to avoid confusion.)  Boot off the CD.
  5. Choose option 7 (Directly start the graphical environment).  Tap enter when its looking for a keyboard map.
  6. Type 'gparted' in the terminal window, and use it to determine what devices are what.  (click GParted, and change devices) Take note of your Hard Drive (usually /dev/sda) and your USB Drive (mine was /dev/sdb).  The partitions/sizes should be a big hint, especially if you have no other drives connected.
  7. Close gparted, and enter the following commands in the terminal window:
    mkdir /mnt/usb
    mount -t ntfs /dev/sdb1 /mnt/usb
    ls /mnt/usb
  8. 'mycloud2tb.img' should be the result.  Time to overwrite everything...
    dd if=/mnt/usb/mycloud2tb.img of=/dev/sda
  9. Be patient.  Your hard drive is being overwritten and that takes some time.  Your result should be
    10240000+0 records in
    10240000+0 records out
    5242880000 bytes (5.2 GB) copied, xxx.xxx s, xx.x MB/s.
  10. If you have a 2TB My Cloud, skip to step 18.  Otherwise, continue.
  11. Shutdown and reboot the CD. I'm not sure you need to, but it was necessary for me, so its in here.  Same options as before, until you have a terminal window.
  12. parted
  13. Enter the following commands in the (parted) prompts:
    unit s
    p
  14. Error: The backup GPT table is corrupt, but the primary appears OK, so that will be used. OK/Cancel?
    OK
  15. Warning: Not all the space available to /dev/sda appears to be used, you can fix the GPT to use all of the space (an extra 39070080000 blocks) or continue with the current setting?
    Fix
  16. We're looking for the start sector of the last partition (4).  I would think it would be the same on 3TB and 4TB, but I can only speak for the 4TB, which is 9428992.
    rm 4
    mkpart primary
    File system type?   [ext2]?
    ext4
    Start?
    9428992s
    Warning: You requested a partition from 9428992s to 7814037167s (sectors 9428992..7814037167).
    The closes location we can manage is 9428992s to 7814037134s (sectors 9428992..7814037132).
    Is this acceptable to you
    Yes/No?
    Yes
    quit
  17. Back to the command prompt..
    sync
  18. Shutdown the PC, and (loosely) reassemble your My Cloud to its mini-board.  Time to boot it and try it out!
  19. (3TB/4TB Drives) Once you get to the dashboard, do a Quick Factory Restore.  This reformats your data partition for the full size.  Once it reboots, DON'T PANIC.  It will show as only 2GB for a short time... eventually, it'll wise up.

Remember, that first boot can take a while...  I even had the flashing yellow light come on the first time (overheat warning?), but I power cycled it and it came right up, no problems.  Don't forget to put it back together!

Hello,

Thank you for posting this guide. Hope it helps other users.

Users please note that as  Ouglee mentioned this will void your warranty and delete all the data stored on the drive.


#3

Awesome job!

Thanks for sharing.


#4

Fantastic, absolute life saver.

Just to add, i managed to do this from a laptop using a SATA/USB connector, i did end up taking out the laptop hd though as i couldn't work out how to change to the correct "unit" in command line parted. but its worked like a charm and mine rebooted showing the full 3.9tb.

again, thank you so much for this tutorial.


#5

I'm glad I could help.. !


#6

CM: Could this get stickied? Pretty sure that it could be improved on, but until that happens, it might just save someone's drive


#7

it sure saved mine after i did something stupid and had no access to the drive at all (web ui or shell)

one thing i think is missing..

on that bit it also asks for and end which is missing from the tut. I tried 7814037167 but that was too high so tried again with 7814037132 and that worked a treat.

Hi and thanks.

End of partition 4 for the 3TB My Cloud is at 5860533134s

thanks for that tut, you safed me, but at 19. i do a quick factory restore and it shows after that 2tb but i have a 3tb. then i restart the cloud and its no change. at the moment i run the complete factory restore but that needs time to say how many tb its show after that.
i used the end of partition 4 that postet user "zelig"

Edit: Complete factory restore is done but it still shows on 2tb. Can anyone help or any ideas?
sorry for my bad english

edit2: I again used parted and the partition table had at the end of a 9th partition with the remaining unpartitioned 1TB. I then started from the tuturial from point 16 again and did "rm 4", "rm 9" run (with "unit s" and look at the partition table "p" if the remaining unpartitioned area has really 9), dannach worked it without problems with "mkpart primary" and the rest of the tuturial.

I hope my text is understandable. I used groogle translator

Hi Ouglee,

Congrats for the detailed tutorial!

I have used it to fix my WD My Cloud 2TB and all the process worked without any error. However, when I powered on the device again, it started to boot until it stopped in a stable red light... I left it for a while (about 20min) to see if it would change, but no change at all.

Do you have any idea on what I can do?

I did the whole image restauration process a second time to see it helped, but I got the same thing...


LED - RED (constant) and i can't see files anymore

Hi,

Just managed to make it work!

What I did different now is:

* Uncompressed the image using linux command line (throught the Rescue CD prompt). First time I had done with WinZip, in Windows.

* Comparing my partitions to the ones you posted, I noticed that I had an "alert" icon in the SWAP and EXT4 and you didn't have it. So, after restorning the image, I formmated both Swap and Ext4 partitions... the icons stayed there, but anyhow, it was an action that I hadn't done in the previous time.

I don't know exactly what was the action that solved the problem, since I have applied both... but one of them (or both combined) made it work.

Many thanks again for the post!

******* And WD Engineers:

For next models of My Could, please include a clean image in a safe partition (or even in an independed internal memory) and a button for a REAL factory reset, in order to make a full restauration and avoid all this problems to your customers.

Hello,

Many thanks for a great solution, which helped me out to recover my brickd My Cloud 2TB (I tried to install pyload before, and someting went wrong.......) .

I recovered my drive using this solution, but now I have errors reported by DISK Smart, on UI on dashboard there is Warning state, and I am still receiving email with below message: 

Message :critical

Code number: 0003

In that same thime while error is occuring the led is changing colour to red.

I don`t know what should I do now.... could somebody help me ?

thanks in advance , for any tips...

cheers, gynox


#13

A SMART error is based on a failing hard drive... I'm not sure what an error 0003 is. Short answer, there isn't any way to clear SMART errors (they report temperature, life hours of the drive, etc). You might try replacing the hard disk itself, but this (and all of these issues) are outside of the scope of this guide


#14

Thanks for answer I found the problem....now :-) 

I loged via ssh to check whether SMART is enabled and fine,  I saw that is disabled - really strange, and unexcepted

I will provide my steps below, maybe this woud be helpful for someone else.

  1. To check smart status via console : 

sudo hdparm -I /dev/sda [there should be inside information about smart]

To enable it :

sudo smartctl --smart=on /dev/sda

after that problem is gone.

Many Thanks,

gynox


#15

Thanks, you save my day!!!

Just to help, this tutorial seems better to me to disassemble.

The ohter one make me brake a smal plastic stuff.


#16

You are My hero. I tryied several ways to bring back to life my My Cloud 3TB without succes. With your advice i actually did it without any knowledge at all in linux etc. 

 After i finished i did a Full factory restore because it only saw 1,5GB free space (which lasted 12+ hours). My Drive is now functioning again like new.


#17

Hey I've done this and it works a peach however one question I have a 3TB drive and doing this now only shows as if it where a 2TB after soft factory reset how do u fix this?


#18

read my last post, there is the solution on page 1


#19

edit2: I again used parted and the partition table had at the end of a 9th partition with the remaining unpartitioned 1TB. I then started from the tuturial from point 16 again and did "rm 4", "rm 9" run (with "unit s" and look at the partition table "p" if the remaining unpartitioned areahas really 9), dannach worked it without problems with "mkpart primary" and the rest of the tuturial.

I hope my text is understandable. I used groogle translator

 I have seen this but I am not quite sure what you mean?

Re run parted on rm 9 this time and not rm4?


#20

Sorry for double post, Solved it I just resized the partition in gparted.

Thanks for the guide
