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.
There are DC UPSes that can supply 12V and are typically used to keep wireless routers and security cameras running for a few hours during power failures. They plug into the mains and are about the size of a 3.5" HDD.
Most USB power banks power cycle when the switch between charging/supplying/pass through mode, so if you use them for computer equipment they will lose power for a few seconds when the mains comes on or off.
Edit: DC UPSes are also much cheaper than standard ones.
Would this be something you’re talking about? It’s the cheapest one I can see on Amazon here in Canada.
