If
/dev/sdXn contains a file system with errors, check forced.
every time you boot and fsck never finds an error, then you need to have fsck run at an earlier stage to fix this.
- Add “fsck” to /etc/mkinitcpio.conf in accordance with the instructions on Arch Wiki’s mkinitcpio page.
- Run “sudo mkinitcpio -p linux”.
- Reboot.
It will update the HDD’s status that there are no errors after this fsck run.
