Who are we?

We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

We are one. We are legion. And we're trying really hard not to forget.

Seagate Expansion external HDD power supply making a very faint alarm sound (self.datahoarder)

I've got a fairly new 14tb Seagate Expansion. It works fine, and I've been using it for a month and a bit.

I don't know how long it's been doing this, but the power supply is making a very faint alarm sound. The power supply is plugged into a Belkin surge protector powered on and with the "protected" status light lit, and it is plugged into an outlet. The HDD is currently not plugged in to a computer.

It's not a beep or electricity. It's a distinct weewooweewoo. I couldn't even determine the source until I pressed my ear against it.

Googling just points me towards typical "my HDD is making a sound, how long do I have until it dies", but nothing pointed me to the alarm sound from the power supply.

I'll check again if it makes the alarm in other conditions, but in the meanwhile, I was hoping someone here might know something.

Thanks in advance!

EDIT: The sound only happens when...

Power adapter is plugged into the HDD, AND the outlet
HDD is NOT plugged into the computer.

Plugging it into the computer stops the noise from the power adapter.

I've come across it once with a laptop power supply. I believe it correlated to a voltage issue of some sort. We just replaced it with a new one and the problems disappeared. It definitely wasn't coil whine, but I didn't believe the person complaining about it until I held it up to my head myself.
