Hi, dggomes & kissu,

I fixed My Cloud just now, and upgraded to the latest Firmware. Now, I am doing a Full Factory Restore.

Please forget the script and rootfs.img, see my below steps:

  1. Download a virgin disk image

    http://community.wd.com/t5/WD-My-Cloud/Here-is-WD-My-Cloud-2TB-virgin-disk-image/td-p/637769/highlight/true

  1. Restore the virgin disk image you downloaded, please follow this GUIDE, only follow the step 1 -15. If your Cloud is a 2TB disk, that’s all! Or, please look forward to extend the last partition to 3 or 4TB.

    http://community.wd.com/t5/My-Book-Live/GUIDE-Debrick-MyBookLive-v2-0/td-p/567582

3. DO NOT USE THE GParted to extend the last partition, I just follow below GUIDE. You need to modify the script to your own (# mkpart primary 9428992s -1 )

    http://community.wd.com/t5/My-Book-Live/GUIDE-Debrick-MyBookLive-v2-0/m-p/571579/highlight/true#M22598

That’s all.

Wish everything goes well!

Please use below script to catch the mount partitions

WDMyCloud:~# cat /etc/mtab

 Umount all the partitions related with /dev/sda4 when you extend the last partition, for example:

/dev/sda4 /nfs/TimeMachineBackup ext4 rw,noatime,nodiratime,user_xattr,barrier=0,data=writeback 0 0/dev/sda4 /nfs/Public ext4 rw,noatime,nodiratime,user_xattr,barrier=0,data=writeback 0 0/dev/sda4 /nfs/SmartWare ext4 rw,noatime,nodiratime,user_xattr,barrier=0,data=writeback 0 0WDMyCloud:~# umount /nfs/Public/
WDMyCloud:~# umount /nfs/SmartWare/
WDMyCloud:~# umount /nfs/TimeMachineBackup/

Great stuff guys, just unbricked mine! MANY thanks for all your help!

I think that the only thing missing in the guide posted is that you need to have your hard-disk clear of all partitions before using the dd command otherwise it will not work properly.

I did this with the following commands from the previous script cnlinya posted (this will delete everything in your hard-disk):

root@y-System-Product-Name:/# parted
GNU Parted 2.3
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) select /dev/sdb                                                  
Using /dev/sdb                                                             
(parted) mklabel gpt
Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you
want to continue?
Yes/No? y

(parted) quit                                                             
Information: You may need to update /etc/fstab.

The erase procedure is only needed if writing image on both raid partition and booting doesn’t fix the softbrick.

If partition layout is correct no need to erase all losing shares and data.

The full image restore should be the last option to recover a softbrick.

this  image is for mybook 3T  ,not for mycloud 3T !! 

any one can upload  the image for mycloud 3T ???

You can download and restore the 2TB image to your 3TB cloud, then extend the last partition to 3TB.

Mine is a 4TB cloud, later, I will post my virgin disk image here.

Rookie mistake - I didn’t read all of the replies :slight_smile:

Hi! I followed the instructions by cnlinya and my WD Cloud works, but if I connect the drive to the PC, it appears as an “unknown” partition table so I can’t mount (or even see) any partition in the drive.

That’s a big problem for me, because even if the unit works, I want to use the linux box and I dont want to loose all my data or have to try my luck with recovery tools if I do some wrong commands and it doesn’t boot anymore.

When you connect the drive directly to the computer, can you see the partitions from there or is the partition table corrupted for you also?

Anyone has a solution for this?

Thanks

Hi miguelkorn87, they were corrupted for me so I could only see the partitions and recover files with the software R-Linux.

40

Does that happen to EVERYBODY or only to the ppl that restored with the image?

Is there any possible way to avoid that??
