Can a power outage kill a HDD?

Computernaut

I was doing some electrical work in my house and had to flip a breaker, unfortunately it was the one that my computer's socket is on (the computer was sleeping at the time). When I turned it back on it booted to my SSD, but my storage HDD didn't show up or work. A restart fixed it but it did get me curious as to whether a sudden loss of power could kill an HDD. Can it?

What is actually supposed to go here? Some people put their specs, others put random comments or remarks about themselves or others, and there are a few who put cryptic statements.

Sudden power loss won't break the HDD even when its active. But it may corrupt the files it's working at the time.

While power loss won't break it, spike surge can.

So then why would it not show up or work when I turned my computer on after the power loss?
