smartd is a daemon that monitors the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into most ATA/SATA and SCSI/SAS hard drives and solid-state drives. The purpose of SMART is to monitor the reliability of the hard drive and predict drive failures, and to carry out different types of drive self-tests. This version of smartd is compatible with ACS-3, ACS-2, ATA8-ACS, ATA/ATAPI-7 and earlier standards.
CLI tool smartctl to investigate disks.
One shot on all devices
Hard disk drive and SSD health inspection tool
GSmartControl is a graphical user interface for smartctl (from smartmontools package), which is a tool for querying and controlling SMART (Self-Monitoring, Analysis, and Reporting Technology) data on modern hard disk and solid-state drives. It allows you to inspect the drive's SMART data to determine its health, as well as run various tests on it.
- Monitored devices:
Examine all entries /dev/hd[a-t] for IDE/ATA devices, and /dev/sd[a-z], /dev/sd[a-c][a-z] for ATA/SATA or SCSI/SAS devices.
- Disks behind RAID controllers are not included.
If directive -d nvme or no -d directive is specified, examine all entries /dev/nvme[0-99] for NVMe devices.
- Entries reporting failure of SMART Prefailure Attributes should not be ignored: they mean that the disk is failing.
- Use the smartctl utility to investigate.

The defaults are probably alright, but you have to test your mail delivery.
If you are using /etc/hosts to set FQDN, make sure the hostname is set correctly (with no trailing dots)
Make sure your aliases are setup correctly
1 root: email@example.com
Translate the aliases
Run a quick check
The default config will:
- scan for removable devices,
- check the device unless it is in SLEEP or STANDBY mode,
- and on failure send and email to "root"
- check if mailx or mailutils are installed
1 # Sample configuration file for smartd. See man smartd.conf. 2 3 # Home page is: http://www.smartmontools.org 4 5 # smartd will re-read the configuration file if it receives a HUP 6 # signal 7 8 # The file gives a list of devices to monitor using smartd, with one 9 # device per line. Text after a hash (#) is ignored, and you may use 10 # spaces and tabs for white space. You may use '\' to continue lines. 11 12 # You can usually identify which hard disks are on your system by 13 # looking in /proc/ide and in /proc/scsi. 14 15 # The word DEVICESCAN will cause any remaining lines in this 16 # configuration file to be ignored: it tells smartd to scan for all 17 # ATA and SCSI devices.
