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.

I can infer that you want suggestions for cost efficient backup power. Depending on the laptop model, it could power the HDD and in case of an outage it could draw power from the laptop's battery. It would decrease battery charge duration but it would be enough for a graceful shutdown to prevent data loss.

Alternatively, you could maybe use a battery pack.

Ive thought about trying this before, but do you have any experience with how to actually hook up the power supply?

Never thought breaking a drive was worth the risk, but theoretically you should be able to solder a buck converter to the laptops motherboard if the voltage requirements vary.
