I own a WD Blue 1TB where I have downloaded several steam games and apps like Mumble. When I last tried to run mumble, it says it was missing, yet I hadn't deleted it. This happens with several other apps and some icons don't appear, they are just a white page as an icon. Does this mean that my HDD is corrupt or am I missing something?
