My Book Essential stopped working

So ever since the new MAC software update, the my book essential external storage doesn’t work anymore. Tried everything, tried updating the firmware thing, says the device is lock and need to unlock it but there is nowhere I can unlock it. When I plug it in the light in front flashes/blinks instead of being solid green and staying that way. Tried different MAC computers with the new MAC OS update and same problem…So is this fixable or what?

If you setup password protection for the My Book the unlock icon should always appear on the desktop for you to unlock it. You can also do it installing Smartware, check the link below for more information.
