Moving from OS3 to OS5 issues- Blinking Blue Light

So a quick background : for a while, I was getting notifications on my MyCloud app and dashboard that I need to upgrade to OS5.
Finally when I actually was doing so, my MyCloud just stopped working in the middle of the process. Here are some of the ’ symptoms’:

  • hard drive can’t be detected
  • blinking blue light (fast) for a few days now
  • dashboard not accessible

I have some important files that were not backed up on the process. I would have just stayed on the OS3 version if I have known this is going to happen. Thanks.

Note there is a subforum where OS5 issues are discussed. this subforum (OS3 My Cloud) typically discusses OS3 (v4.x and v2.x firmware/device) issues.

May want to dig through the following WD Knowledge Base Article on OS5 to see if any of the compiled articles apply to your situation. It sounds like you may be experiencing the “indexing” issue that cripples and renders unusable some My Cloud devices when they’re updated to OS5.
