My Cloud Personal led flashes red, does not connect to network

I have a My Cloud Personal which appears to have failed sometime around a power outage. It no longer shows up on my LAN.

Symptoms:

  • The status LED at the front now blinks red rapidly
  • The network port light is green and intermittently flashing green (which looks like a proper network connection)
  • The device does not appear on my LAN: the router’s UI shows that the My Cloud’s MAC address is not connected

This drive is pretty old, and I have up-to-date backups of at least the important stuff, so it’s not a catastrophic loss; still, I’d like to see if I can fix it, or at least mount the drive somewhere and recover the data locally rather than having to restore from the cloud.

Does anyone have any advice on troubleshooting the network connection problem? It had been connecting to the network through a small switch to a Deco Mesh node.

  • Other devices on the same switch are operating normally
  • I’ve swapped ethernet cables with a known working device; this device works fine with the My Cloud’s cable, and the My Cloud still flashes red
  • I’ve tried bypassing the switch and connecting the ethernet cable straight into the Deco router. No change: light continues to flash red, port flashes intermittent green, and the Deco still considers the My Cloud’s MAC to be offline

This all leads me to believe that something got damaged in its electronics when I plugged it back in after the power outage ended.

I even checked the power supply, and it’s providing steady 120V like it should, so I don’t think that’s the problem.

Is there anything else I could try?

It’s an older version of this: Amazon.com: WD 4TB My Cloud Personal Network Attached Storage - NAS - WDBCTL0040HWT-NESN : Electronics

Here is the link to the first generation WDMYCLOUD single bay with OS3 User Manual. Look at LEDs.

This device can only be used on your Local Area Network. Is this what yours looks like? Do you know what Firmware is on it?

Mine is set up for use on my Home Network.

The manual doesn’t list anything for the LED being red and blinking, but I assume it’s a mistake, and it corresponds to the following:

The following faults trigger this state:
• Disk SMART failure
• Data volume does not exist
• System volume does not exist
• System thermal shutdown (75 C)

That’s what my device looks like. I don’t know how to verify the firmware version, since I’m unable to get it onto the LAN anymore. Is there some other way to connect to it?

Look at this User Manual for the second generation and check LEDs. Did you update to OS5 or stay with OS3?

My Cloud OS 5 Online User Manual

The P/N number indicates you have a second generation single bay My Cloud. The second gen single bay My Cloud supports OS 5. The following link is the proper subforum for single bay My Cloud OS5 discussion.

The user manual for the second gen single bay My Cloud can be found at the following link.

Typically a flashing front red LED means a hard drive problem. If one cannot access the My Cloud Dashboard by the device’s name or by it’s IP address. One can try to extract the hard drive from the single bay My cloud enclosure and connect it using an SATA adapter to a computer running Linux, or which has Linux drivers installed. From there one can check the drive for errors and or retrieve user data if the data partitions are accessible.

There are various methods to install a new hard drive into the single bay enclosure. The following links has one way, directions and files, to restore a second generation single bay hard drive.

@cat0w I upgraded it to OS5 some time ago.

@Bennor thanks for the tips. I figured as much. Sorry for posting in the wrong forum.
