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?


This is my HDD. Aren’t these guys able to handle power losses since people usually plug them in to backup stuff, and then pull the plug once they’re done?
And does ext4 count as a journaling file system?
