Unbrick mycloud 1 bay gen 2

Still No luck, it’s on 0%.
do i need to map the USB as well with Recovery files on it?

A suggestion as a troubleshooting step. Try using a Windows PC to create a single partition covering the entire disk, then format it for NTFS. Then try running through the unbrick procedure for the single bay gen 2.

I found that in one strange incident on gen 1 single bay that one specific hard drive for what ever reason wouldn’t properly unbrick unless I partitioned and formatted it on a Windows PC first. Probably related to what Fox_Exe is suggesting above to erase the initial sectors/space on the hard drive. In my case I had to partition the drive to MBR not GPT and format it for NTFS. Then use Linux to repartition and format per the unbrick instructions. Not sure why only that one hard drive was problematic but it was.

Thanks mate, let me try that and get back to you.

one thing i need share, after making partition when i press “q” to quit. i get below

Information : You may need to update /etc/fstab

Still, No luck, tried with older firmware and ran all commands as suggested.

still on 0% from last 2 hours.

Lets step back here. What directions are you using to unbrick your second gen My Cloud?

If following these directions: https://fox-exe.ru/WDMyCloud/WDMyCloud-Gen2/_Unbricking_en.txt Are you using the first method or the alternate method?

Rather than trying to upload the very latest v2.x single bay My Cloud firmware try using an older version as a troubleshooting step if you haven’t done so already.

i am following the alternative method from above article and using the very first firmware released “My_Cloud_GLCR_2.10.302.bin”.

Alternative way:

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:

Typically message means that one may have to restart their Linux OS PC so that the Linux OS will properly see and uses the newly created partitions on that hard drive.

Other troubleshooting suggestions. Use GParted within the Linux GUI to remove all partitions on the hard drive. Then use GParted to create one single partition. Then when following the unbrick steps use “parted” to remove all existing partitions first, then follow the steps to create the required partitions for the My Cloud OS structure. Also as a troubleshooting step, remove any other hard drive attached to the PC other than the My Cloud drive to avoid any possible issues. Check the drive for SMART errors or physical errors.

Not sure it’s been asked but what hard drive are you trying to use to perform the unbrick procedure on? In other words; what make/model hard drive will be put into the My Cloud enclosure? Wonder if the issues you are having are specific to only that drive. Don’t recall anyone having such issues repeatedly while unbricking using Fox_exe’s directons using either the main 2nd gen unbrick method or the alternate method.

Hi @Bennor- I am using the WD NAS drive which comes in My Cloud.

i have checked it doesn’t found any errors.

let me perform the steps suggested by you now.

i just noticed that after making partitions in Gparted all partitions are showing as unknown, do i need to format them before i assemble in WDMC:

@Jorawar, something wrong. Partition 3 must be formatted in Ext3 (or ext4) format and contains “boot” folder with uImage and uRamdisk files inside.

When following the alternate direction steps, have you performed the following step after quitting mkpart where indicated in the alternate directions steps? Example using your /dev/sdb layout:

mkfs.ext4 /dev/sdb3

The mkfs.ext4 step will format /dev/sdb3 as EXT4. From there you can copy, as the directions state, the appropriate files to folders you create on that EXT4 partition.

Per your screen capture it appears you have formatted the wrong partition for EXT4. Your screen capture shows partition 2 (/dev/sdb2) rather than partition 3 (/dev/sdb3) being EXT4.

@Bennor @Fox_exe - I followed below Link and i am able to unbrick my disk:

i was following Fox’s method but it doesn’t work, so just concern when we create the partitions do we need to format the other partition to some specific format?


because as per Fox’s method we are only making SDB1 as “mkswap” and SDB3 as “ext4”

might be the it is causing the issue as other partition are “UNKNOWN”

should i format the partition to specific format before putting it to WDMC and Boot UP?

@Bennor @Fox_exe-

I am able to unbrick with above link, but getting below issues:

1 Not able to Make Static IP
2 Not able to Change Drive Name
3 Not able to Change admin user name.
4 Not able to access the drive over WD My Cloud app or web portal.

as soon as i reboot, it turns back to default.

@Fox_exe- Please confirm, with your method do i need to format the below partition before booting up with WDMC?


After performing the unbrick procedure, if you can access the My Cloud Dashboard but there are still errors or issues. One troubleshooting step is to perform a System Only factory restore via the My Cloud Dashboard > Settings > Utilities. If after a System Only factory restore the issues persist, try performing a Quick Restore.

Note a System Only restore does not delete user data. But a Quick Restore will delete all user data.

i tried doing Quick Reset, it end up with bricking the drive again.

quick reset stuck at 98%and Full Reset stuck at 31%.

Please confirm, with your method do i need to format the below partition before booting up with WDMC?


While I do not have a second gen single bay/single drive My Cloud, on a first gen one does not need to format most of those partitions. On a first gen the SDB1 and SDB2 are linked together to create MD0. SDB3 is set as a swap partition. SDB4 on the first gen is the main user data partition. Which is why on a first gen one formats SDB4 as EXT4.

On a first gen one does not need to format; SDB1, SDB2, SDB5, SDB6, SDB7, SDB8. One is pushing the rootfs.img file to MD0 (SDB1 and SDB2). On is pushing the kernel.img file to SDB5 and SDB6. One is pushing the config.img file to SDB7 and SDB8.

However, one generally performs a different method to unbrick a second gen v2.x single bay My Cloud. It is quite possible something similar ultimately happens. That certain img files get pushed to certain partitions.

These partitions will be formatted by WD Firmware installer later.

Not sure, what i am doing wrong then…

It is going to be a really stupid question. But are you sure you have a gen 2 single bay/single drive My Cloud? Check the P/N number on the bottom of the My Cloud enclosure, a second gen’s P/N should be something like this and end in a “-10”: P/N: WDBCTLxxxxxxx- 10
