MyEX4100 still blue blinking after 40 sec reset

After 40 sec reset MyWDEX4100 continue blinking more then 15 min.
What have I do (I have never powerof-ed yet) to renew my WD?

Hello,achechet,

Well, there could be multiple reasons for the blinking LED more than 15 min I would request you to try contacting WD’s Technical Support about this.
