My Book Live 3TB

After working perfectly fine for a week now suddently this morning i checked on my network and it wasn’t there.

Went to the external and it had a red light. So i unpluged it, and put it back on it started as a blue light after about 1 minute it turned to the red light, i switched the ethernet cables and spot from the back of the router to a different spot but it still did the same thing, any suggestions?

Check page 12 of the manual.  RED indicates a drive failure or other internal fault such as overheating.
