Simple cron script that checks meaninful smartctl output, so to detect all possible errors on your drive, not just the PASSED/FAILED overall-health self-assessment test result
In case of anomalities the script prints all status bits as in https://linux.die.net/man/8/smartctl (see "Return Values")
Download the script https://raw.githubusercontent.com/francescor/check_smartctl_output/main/check_smartctl_disk_status.sh
then
# adapt `DISKS_TO_CHECK='/dev/sda /dev/sdb /dev/sdc /dev/sdd'
# with the list of your disks
# make it executable
chmod +x https://raw.githubusercontent.com/francescor/check_smartctl_output/main/check_smartctl_disk_status.sh
# add a cron job, something like:
00 9 * * * /root/scripts/check_smart_disk_status.sh
