To initiate a HDD test run following:

smartctl -t long /dev/<yourdevice>

It will tell you how long it takes, do not disturb it, I have seen test
interrupted when running smartctl - /dev/<yourdevice>.

Afterwards I usually run

smartctl --all /dev/<yourdevice> | grep -e "Reallocated_Sector_Ct" -e
"Current_Pending_Sector" -e "Offline_Uncorrectable" -e
"UDMA_CRC_Error_Count" -e "Hardware_ECC_Recovered"

to get the most important readings.
