We lost power for a half hour or so. Now my EX4 refuses to boot. The front panel just says “Welcome to WD My Cloud EX4,” but no disk activity, and no response to any of the front panel buttons. I’ve tried pulling the power input for a while and then re-inserting. No improvement.
The thing semi-regularly freezes up like this, but cycling power has always gotten it back. Now it’s just a brick with a small static readout on the front.
