How to auto remount external HDD after power loss to laptop server? (piefed.ca)

I'm running a Ubuntu server on my old laptop with an external HDD connected to it. The external HDD is powered independently from the laptop, as it is plugged into the wall.

During a power outage, my laptop remains operational due to its battery, but the HDD shuts down. When power is restored, my laptop does not automatically remount the HDD, and I have to reboot the system manually to access it.

Does anyone know how I can resolve this issue?

Edit: Not sure if this added context changes anything, but this is the HDD I'm using. It's a 3.5" HDD that gets its power directly from the wall.

My /etc/fstab file currently has the following:

UUID=412ea77a-96e1-427c-9f75-2aae2fe0dca1 /mnt/wd ext4 defaults 0 2

If I were to use the mnt-data.mount you've suggested, does that mean I need to delete what I already have in /etc/fstab and replace it with what you suggested?
