Stirbt die MyCloudEX2Ultra?

The question of whether the WD My Cloud EX2 Ultra is "dying" is on the minds of many users, especially given repeated issues after firmware updates and the switch to My Cloud OS 5. Numerous reports in forums and communities indicate that the device's reliability has declined in recent years.

🔄 Common problems with the My Cloud EX2 Ultra

1. Firmware updates cause malfunctions

Some users report that automatic firmware updates can cause significant problems. One example is a case where error messages such as "Power supply failure" and "Volume 1 is degraded" appeared after an update, even though the hard drives were healthy according to diagnostics.

2. Access problems after Windows updates

After updating to Windows 11 version 24H2, some users were no longer able to access their NAS. The cause was disabled protocols such as NetBIOS or SMB1, which are required for communication with older NAS devices. Enabling these protocols restored access.

3. Error messages and RAID problems

Some users received critical error messages such as "System temperature too low" or "Volume 1 is degraded," even though the system temperature was within normal range. They also experienced problems rebuilding the RAID volume, indicating possible firmware errors.

4. Access denied after incorrect password entry

One user reported that after entering the wrong password twice, access to the NAS was permanently denied, even after entering the correct password. This suggests possible security mechanisms blocking access after multiple failed attempts.

🛠️ Possible solutions

Perform firmware update manually: Instead of allowing automatic updates, a manual update to a stable firmware version can help avoid problems.

Check network settings: Make sure that all required protocols (e.g. SMB1, NetBIOS) are enabled, especially after operating system updates.

Perform system diagnostics: Use the NAS's built-in diagnostic tools to check the health of the hard drives and the system.

Factory reset: A factory reset can help resolve persistent issues. However, keep in mind that this will erase all data.

📉 Conclusion

The WD My Cloud EX2 Ultra has historically enjoyed a solid reputation as a reliable NAS device. Recently, however, reports of issues following firmware updates, compatibility issues with current operating systems, and other malfunctions have been increasing. While some of these issues can be resolved through technical adjustments, the overall situation suggests that the device is increasingly reaching its limits.

For users who rely on a stable and future-proof NAS solution, it might be wise to consider alternative devices that are more compatible with current software and security standards.
