Rebuild your My Cloud or upgrade the HDD on it

Legacy Products My Cloud OS 3
1

This is what I did to rebuild my drive from soft brick. You can use this to upgrade your My Cloud to whatever side you want.

This thread helped me:  http://community.wd.com/t5/WD-My-Cloud/Here-is-WD-My-Cloud-2TB-virgin-disk-image/m-p/668617/highlight/false#M5968

Got the image. Used Ubuntu and restored it to the drive. All I have to do now is to resize the ext4 partition - sda4 and I’ll be back in business again :slight_smile:

This is what I did:

-load up a live Ubuntu drive on a computer and attach the WD drive to the machine - take ie out of the case and use a USB adapter or a SATA/ESATA cable.

-download the image from the link above and extract the IMG from there.

-start Disks application and select the WD drive.

-click on the gear and select ‘restore from image’ for the whole drive

-point to the downloaded image

-run fsck on the 4th partition

          -for me, the device was mounted as SDA

          -fsck /dev/sda4

-start GParted and extend the sda4 partition to fill up unused space

-put back in case and boot up :slight_smile:

You now have a fully working drive in ‘just out the box’ condition.

EDIT: Here’s the 3TB image.

https://www.dropbox.com/s/yrwgwko2wfraolw/mycloud3T.7z

Use this for a 3TB drive and skip the GParted part. I still recommend doing a fsck.

My guide should work on any size drive, so you could theoretically put in a 6TB drive in the enclosure and you should be able to set it up using this guide.

I hope to not have to use this, but thanks for the instructions

gave you a kudos for sharing this… Good to know when I upgrade it to a 8TB drive someday :stuck_out_tongue:

Has anyone tried to set up the system on a smaller disk say 500gb?

I took out the 4tb disk because i’m afraid it wont live long considering the stand by problem so i’m interested only in making my cloud a torrent downloader. 

6

How did you open up your my cloud case? Where are the tabs to allow the HD to slide out?

7

It’s in deed very difficult but i managed to get the disk out of the case. The problem for me now is to install a new system on a 500gb disk.

Can you describe how you opened it?

got ideas from this   http://www.youtube.com/watch?v=TGLJi66vxnY

it’s quite similar procedure

I have known that I could do it by connecting directly HDD`s sata port to a computer.

but my question is: can I do it without opening mycloud`s case and taking out the hard disk drive?

I mean by connecting my cloud`s USB port to a computer ?

does your computer recognize the drive if mycloud does not boot up (becuase of firmware problem) ?

tnx

The following command creates an empty fresh filesystem:

mkfs.ext4 /dev/sda4

After that you can try to boot on MyCloud, and if you are lucky you get blue LED :smiley:

UPDATE : After all that came up on screen and stood @ ubuntu@ubuntu:~$, I just shut the pc, put the PCB on and up and running .

hello,

firstly, i wanna say thank you for this! i wanted to swap out the Red drive with a Green one in the MC.

The image worked for me but i cannot run the fsck, because it is telling me that i either need r/w acces or i need to beroot.

i am perfectly noob to linux, so dont know how to set either of those. im using linux mint, can you please help with this?

thanks in advance!
