I have a WD MyCloud Mirror - its flashing blue light on power led followed by orange light continually. I’ve tried the 40 second reset with no luck.
Has anyone any advice or tips ?

Tx in advance

The MyCloud Mirror has its own subforum but the Gen 1 device is pretty much identical to the MyCloud EX2 and the Gen 2 device is pretty much identical to the MyCloud EX2 Ultra.

Actually booted up finally but now has failed disk I need to replace. Probably need to get a solution based on SSD at some point.
