Today’s hard drives have a technology known as SMART (Self-Monitoring, Analysis and Reporting Technology System), which allows the storage device to continuously check its status and, in this way, notify the user in case of detecting any irregularity or error.
Monitor the health of your hard drives
Smartmontools, also known as S.M.A.R.T. Monitoring Tools, is a collection of small utilities designed to monitor hard drives that we have installed in our equipment, in order to know the state of health of any of these devices.
It is possible to perform testing with SMT, schedule automatic disk monitoring or search for malfunctions. These tools do not have a graphical interface so all actions will have to be done via command line.
