Sometimes a younger drive fails prematurely. The rated lifetime is kind of
statistical, most drives last far longer, some die sooner. Though it sounds
like it's just normal file system corruption from power failure.

In the meantime, surge protector power strips may be a good investment?
They're comparatively cheap and I've heard good things. It might help to
avoid damage to components when the grid has issues.
