SMART test
There are three types of self-tests that a device can execute (all are safe to user data):
- Short: runs tests that have a high probability of detecting device problems,
- Extended or Long: the test is the same as the short check but with no time limit and with complete disk surface examination,
- Conveyance: identifies if damage incurred during transportation of the device.
Run test in foreground mode:
smartctl -t short -C /dev/sdd
View test results:
sudo smartctl -l selftest /dev/sdd
