Flashing white light

Hi, i have problems connecting to my cloud so i turn off the power and have it reboot 

now it is stuck on a flashing white light status. i cant see the device on my mac. 

Help please

Leave it plugged in for alteast 24 hours (even 40 hours for some people) like that. If it doesnt get blue LED then you would need to escalate to WD support if under warranty or follwow debricking steps…etc
