S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology)

These are the basic commands to monitor and analyse the hard drive health state. First things first, install smartmontools if not installed.

• List the drive infos : smartctl -a /dev/sdx

• Get the brief status of a disk : smartctl -H /dev/sdx

• Get the temperature infos if the drive is SATA : smartctl -l scttemp /dev/sdx

• Start a drive test, it is possible to make a short, long, offline… test: smartctl -t short /dev/sdx

• Read the last selftest data: smartctl -l selftest /dev/sdx
