WD SmartWare External Drive on Mac 10.10.3

External Drive working fine until I upgraded to Mac OS 10.10.3 (Yosemite).

Power light is blinking, but storage lights NOT on.

Tried powering on/off … no luck.

Icon appears on desktop.

Drive NOT locked.

Appreciate help!


Hi and welcome to the WD community.

Have you tried the drive on a different computer or a different port?
