If you haven’t already, double check the My Cloud network settings to ensure the My Cloud is using the same workgroup name as the rest of the devices on the local network. Also ensure the IP address the My Cloud has assigned is in the same IP address pool range (example: 192.168.1.x / 255.255.255.0).
Also, if you haven’t already done so, perform a 40 second reset. It is generally or typically recommended one do a 40 second reset after unbricking their drive.
On the Windows PC’s ensure the firewall isn’t blocking access to the My Cloud or local network. Also while the following is for Windows 10 some will apply to Windows 7; see, if you haven’t already, the following post and pay attention in particular to steps Windows 10 Specific Method 1 through Windows 10 Specific Method 5.
I have just installed a replacement 3tb drive in a v2 MyCloud, using the “alternative” method of this guide. If anyone else has a gen 2 MyBook, this may come in handy
Format a usb stick as fat32. Not NTFS or exFat. Fat32.
Copy the 2 files to the fat32 formatted usb stick
Insert the usb stick in your pc
Do what it says here:
Use Debian/ubuntu or any other linux distro (USB/CD Live image)
All “/dev/sda” change to your disk! (List disks in system: “parted -l”)
If this is new disk or damaged (formatted) old, recreate partitions first:
parted /dev/sda
mklabel gpt
mkpart primary 1049kB 2149MB
mkpart primary 8591MB -1MB
mkpart primary 7517MB 8591MB
mkpart primary 2149MB 3222MB
mkpart primary 3222MB 4296MB
mkpart primary 4296MB 6443MB
mkpart primary 6443MB 7517MB
q
mkswap /dev/sda1
mkfs.ext4 /dev/sda3
mkdir /mnt/boot
mount /dev/sda3 /mnt/boot
mkdir /mnt/boot/boot
cd /mnt/usb
cp uImage-wdrecovery /mnt/boot/boot/uImage
cp uRamdisk-wdrecovery /mnt/boot/boot/uRamdisk
Done. Connect disk back to WDMC and turn on.
After few minutes WDMC boots to “WD Recovery”. Go to webgui and upload official firmware.
Done!
Thanks to whoever wrote the guide. It just needed updated a little bit. I hope this helps some of you have a successful outcome.
Ok, for some reason my cloud stopped mounting my 3tb partition. So I wiped the drive to start again, but this time when I got to creating the swap file once the partitions had been created (mkswap /dev/sda1) I got an error message: cannot open /dev/sda1: Device or resource busy.
Gparted shows /dev/sda1 as a linux-raid file system, with a key beside it, and a mount point of /dev/md127. I cant unmount the partition or the mount point.
Hi. Sorry, I don’t speak Italian but hopefully you can read this with Google translate.
Have you used the same make and model of drive as the original? I think this is important. I had to build mine from new as I just bought the enclosure from eBay. But my v1 has a WD red so I bought one of those for the v2, and it worked. I followed the guide exactly and it worked first time.
No i try with Seagate hard disk 4Tb. But i don’t know if the problem is the model. I build all partitions same in the online guide for gen2 (i find only guide of Russia). I copy I want know if WD Company had A guide for replace the mycloud when the hd is broken. If you can a link for .img mycloud 4Tb (single hd). Or if there is another system (by back usb) for replace my cloud.
I tried the following step. It work for my cloud (Gen2) 3TB. I am not sure why I need to do twice on partition with different kernel uImage and uRamdisk. However, it works in my device.
I think if you go back and look at the instructions. It shows two ways to unbrick
the My Cloud. One way you take the disk out of the case. The other you use
a bootable USB with the recovery files without taking the disk out of the case.
I followed the process using the USB drive and I am getting the same error than ryop. When I enter in the recovery mode I upload the latest firmware, but when I log into I only have available 0MB.
I used RAID assistant and now it shows the right ammount of TB, but when I restart my device I got again the 0MB. Becaouse of the RAID assistant formating the drives, I cannot store anything in muy WD MyCloud Gen2, becouse when I restart it I loose all my data as I have to initialize again the drive.
Thanks you very much for your reply. It worked! But now it sais me that there is a problem with the unit and SMART. I attach a image; it’s in spanish, but essentially it sais that there is an error with the disk SMART unit while autochecking the disk 1.
That means that the drive is reporting a hardware failure of some kind. (Excessive read errors/bad sectors reallocated, drive exceeded manufacturer specc’d max temperature, Excessive concussive shock was detected, etc.)
The drive itself is saying “Hey, Wait bro-- I am not reliable anymore!”
That is the purpose of SMART. Really, you should use a brand new disk, and if it his WAS a brand new disk, you should contact replacement services from the drive’s manufacturer to get an RMA process going.
Hi all,
After reading a lot on My Cloud Gen 2 (single drive)HDD change issues, I finally got a HDD upgrade from 4TB to 8TB to work. I had trouble with firmware requests, wrong implementation disk images, corruption of drives. and red lights. But now its working flawlessly.
What did work:
Optional: Cleared the old 4TB drive of all files, to make the images smaller and faster to work with. You can also save a configuration file to upload later.
Put the old drive in an external case and use Clonzilla to get a copy of ALL 7 partitions of the drive. remember to use compression in the main (large sda2) partition. If empty you will only need a couple of GBs to store all images. Remember to use the option to test & fix partitions (else it will fail since we do not have a working Shutdown in the MyCloud).
Put the new (8TB) drive in the external case, boot linux/ubuntu/etc and create the new partitions::
parted /dev/sda
mklabel gpt
mkpart primary 1049kB 2149MB
mkpart primary 8591MB -1MB
mkpart primary 7517MB 8591MB
mkpart primary 2149MB 3222MB
mkpart primary 3222MB 4296MB
mkpart primary 4296MB 6443MB
mkpart primary 6443MB 7517MB
q
mkswap /dev/sda1
mkfs.ext4 /dev/sda3
Boot Clonezilla and restore the 7 4TB partitions in the 8TB disk (in proper order/matching). Clonezilla will adjust the last physical partition (large sda2) to use all available disk space.
Put new 8TB drive in MyCloud case and power on.
Login to MyCloud. There should be a screen where you can opt for Raid or JBOD configuration. Choose JBOD. The disk will be tested and formatted and mounted. You can now create your shares and upload your configuration file.
I used Clonezilla Live 2.4.2 , MyCloud Release 2.31.183, and Ubuntu.
