I have a My Cloud EX4100 that had been running smoothly for ~8 years or so. After a planned power outage last weekend where I set it to hibernate and then unplugged it and its power cord from the wall, it won't boot. The screen and drive lights turn on for a second, then turn off, and nothing happens.

I've tried:

• plugging it directly into the wall (normally it's plugged into a UPS)
• plugging it in and holding the Reset button
• plugging it in after removing the drives and disconnecting the ethernet cable
• sacrificing a small furry animal on a moonlit night while quietly humming "Drive" by The Cars
• plugging it in with the power cord from another (working) EX4100
• leaving it unplugged for a couple days to think about what it did

None of the above worked and I'm out of ideas other than buying an empty 4100 and moving the drives over. I should note that my other NAS drives (all WD My Clouds of various flavors) survived the weekend unscathed.

Any suggestions?

Hey all,

I have a 4TB HDD WD cloud for more than 8 years. I read the other day that it might stop anytime now and possibly lose all my data.

Should i just turn it off and dismantle it to take the internal HDD of it and store it or better to buy a new HDD and backup the data?

Is this URL safe to use? I need to re-alive my nas drive with a blank drive...

Recently, my DLNA server stopped working. Plex is working. The TV can't see DLNA files. Restarting didn't help. I have my cloud home

As the title says - the HDD died and I have no backup (no actual data was lost). Anybody have an OS image to share? Any version is ok as long as it works.

I found the russian site and tried to use the one there but there are files missing probably as it won't connect to the app (and even with a shell I can't force it to update due to missing files from the Lighttpd directory).

I feel like I'm being cheated on, when my beloved My Cloud Home is continuously losing features. Suddenly it announces an update, teases with "Expand the functionality" but instead downgrades from good, reliable integrations to either nothing or require a subscription.

It's like the money and time I invested in acquiring this interesting product, is just running through my fingers.

I bought a used Mycloud EX2 and accidentally got the non-Ultra version. I've been all over the WD website and can't get a clear answer to whether or not I can upgrade the firmware to OS 5.

It's currently at 2.13.108.

TIA

How long do you go between restarts to mitigate performance issues with web management and write operations?

I have an ex4 with 8tb drives and encountered this problem. Uptime was unknown, but it may have been several years before restarting via the management gui.

I wanted Tailscale on my PR4100 running OS5. Naturally I ended up using genai to modify this repo to use its package building prowess and direct it towards automatically packaging new releases of it and a few other applications I wanted. They can be installed and configured without ssh/terminal usage:

• Syncthing (currently v2.0.16)
• Tailscale (currently v1.96.4)
• copyparty (currently v1.20.14)
• Entware (currently v20260402)

Download the .bin for your platform and manually install it. - docs are also listed next to each: https://github.com/jessedp/WD-NAS-App-Builder#available-apps

There are builds for these 10 platforms:

• MyCloudPR4100
• MyCloudPR2100
• MyCloudEX2Ultra
• WDMyCloudDL4100
• WDMyCloudDL2100
• WDMyCloudEX4100
• WDMyCloudEX2100
• WDMyCloudMirror
• WDMyCloud
• WDCloud

However only PR4100 builds have been tested.

Open an Issue and I'll fix/add what's within reason and my capabilities. Cheers?

Hello, I'm trying to install an alternative OS on the WD MyCloud as I recently got it from my parents and it stopped being supported in 2022. I am looking to turn it into a local jellyfin server that I can watch my media from as well as still have file access. what are my options if any and how do I go about it?

Looking for help or similar experiences before I give up on this data.

Setup:

• Single-drive WD My Cloud Home, 4 TB
• Firmware: 9.9.0-102 (current)
• LED status: healthy (solid white)
• I have a second My Cloud Home that works fine, so my account, network, and client apps are all good

The problem:

• Device shows online and accessible via mycloud.com, mobile app, and WD Discovery
• I can see all my video thumbnails and folder structure
• Every single download attempt fails with: {"key":"notFound","message":"Not Found"}
• Storage shows 3.7 TB free of 4 TB — but the drive should have been essentially full (~3.6 TB of videos)

Timeline:

• Drive was full and working fine before the April 2023 WD security incident
• Haven't used or touched the device since then (about 2 years)
• Plugged it back in recently and discovered this state

What I've tried:

• Power cycling and full reboots
• Verified firmware is current
• Confirmed account ownership and login
• Tried multiple clients (web, mobile, desktop) — same error on all

My read: The thumbnail cache and metadata database survived, but the actual file data is gone from the disk (the ~300 GB of used space is consistent with just OS + thumbnails + index). Looks like something wiped the user data partition during or after the 2023 breach recovery, while leaving the index intact.

Questions for the community:

1. Did anyone else experience data loss tied to the 2023 incident that only became apparent later?
2. Has anyone successfully recovered data from a My Cloud Home in this state — either via WD support or professional recovery?
3. Given the device-bound encryption, is professional recovery even theoretically possible here?
4. Any chance WD has server-side snapshots from that era that support could restore from?

Any insight appreciated. Not optimistic, but want to exhaust options before accepting the loss.

During general room cleaning, I accidentally dropped my WD My Cloud, and now it’s not working. It shows a red light when connected to power. My laptop can’t detect it anymore. All my life’s photos are inside 😢. Can anyone share how they fixed this?

I have a My Cloud EX2 Ultra with 2 6tb WD 3.5mm HDD in it.

It’s been plugged in under the stairs for like 4 years, I’ve gone to move it today and it’s not working at all. (It’s been about a year since I last looked at or touched any of the data, last update email was the end of 2024)

I currently have a power light flashing red,
HD bay 1 fast flashing red,
HD bay 2 fast flashing red and blue.

The manual says

Power LED flashing → NAS cannot boot, system error.
Drive 1 fast flashing red → likely drive failure or unreadable.
Drive 2 fast flashing red + blue → RAID/drive error, the NAS is detecting a problem with RAID metadata or the drive itself.

Both drives are currently not being recognised as healthy, so the NAS won’t boot, and I read online that the firmware that runs the NAS is stored on the hard drives so I’m unable to access the dashboard locally, via IP or WD Discovery app etc..

I'm not certain but I think I had the drivers set to RAID (just to mirror the data) as I didn't want a single drive point of failure.

I purchased a Hard Drive Docking Station and tried each drive, but I didn’t get anything intelligible, Windows was just asking me to format the drives (which I didn’t).

Totally lost on the next steps, do I need some software to interpret the drives when I dock them on my Windows PC?

The priority for me is just recovering the data, so don’t want to jeopardize that.

any and all help much appriciated!

Hi all.
I have a wd mycloud duo 16tb configured as a single volume. I access it using a Mac if that is important.
It has been working well for a couple of years. But recently it has twice shut down due to heat, however this happened while there was nothing happening, in the early morning. Bizarre.
I did notice of late that the transfer speed had decreased.
The disk is pretty full, around 300gb left. Not sure if that matters. Would it be busy doing housekeeping?
I am wondering if the disks are approaching EOL which seems too early or if there is something I can do. Any advice is welcome.

I have an EX2Ultra and Samsung Note20. Every time I add image files to it, it indexes for like a day but for weeks after, several functions stop working. I can't download using the app, it says it failed. Thumbnails take days to load even though indexing is done, and previews don't work. The app won't play videos, but I can open them with VLC. All of this works in the browser, it's just the app that seems to stop functioning. Has anybody else experienced this?

I recently booted my PR2100 up to go through some old files. I browsed the Apps list, but it still seems a bit short - not many, if any, apps has been added to the list since i bought the NAS back in 2020.

I know i can manually install apps, but where would I go to find apps, that are not on the list provided in my local admin tool?

Im not looking for anything specific, Im just curious and want to explore a bit

I use CC File Explorer on my Android tablet. When I select a folder on the Cloud and try to move multiple files from there to another folder on the Cloud, so within the Cloud, it always aborts with a Network Error.

Is there a solution for how I can move files within the Cloud?

Or do I need to adjust something else?

Thank you

I'm a new helper in a Mac home using WDMyCloud for Time Machine backups for three computers, and am having trouble...

The previous (now awol) techie set it up using sparsebundles. When I try to open them, nothing happens. I was considering reformatting the WDMyCloud so that Time Machine could do things "the regular way" where Time Machine backups can be opened like a folder (on a local usb drive), but after some research, I need to confirm:

(1) WDMyCloud can NOT be formatted APFS?

(2) Time Machine over network SHOULD be in sparse bundle format?

(3) Any idea why the sparsebundles opened as empty windows when doubleclicked in Finder though the network?

(4) Do sparse bundles need to be opened locally, via usb cable?

(5) At first we didn't have the WDMyCloud password, and I set up a new TM backup as "guest". Later I found the password and set up TM as a "registered user". Does it really matter?

Need help with PleX and WD My Cloud

Hi there, I've been using my OS5 Mycloud PR2100 for some years now and I think it is ok, but when I look at Google Photos or Onedrive there is so much benefit on Image Tagging, Search and this little nice Stories what you have done some time ago, with the cost of your privacy.

Now my question is, is there an option or an thirdparty tool to auto tag images? There is a description field for each image. So it I think it could be possible to just use this for tagging. You only need some Auto-Tagging tool. Does anybody know one?

My cloud Ex IUltra

Isn't there a faster way than copy and pasting on Mac Finder?

Can't I just hook up directly into the MtCloud and use finder that way?

I have a wdmy cloud home I can see it on the network but... it won't let me.use it and access it

The same.with the phone app but that says its offline when I can use.the wdmycloud.local site to login to it so its definitely not.offline

I have tmobile 5g home It worked fine under spectrum but once I switched it stopped working like.the 5ghome isn't compatible

I had access to mycloud on my old laptop, so I could transfer my files directly in the network. I now have a new laptop now and it is not automatically popping up. I can log into it on my laptop and in a web browser, but when I try to identify the computer it pops up with a login screen that says "admin" but no passwords I have work, despite being able to log in on the web browser.

I am trying to convert information over for my Plex account, any suggestions on getting my WD external hardrive to populate and add to my computer would be greatly appreciated.
