Smartmontools, also known as S.M.A.R.T. Monitoring Tools, that belongs to the so-called sniffers, is a collection of small utilities developed to monitor the hard drives that we have installed on our computer, with the possibility to know the status of any of these devices.
It's possible to carry out SMT tests, program the automatic hard drive monitoring or search for working errors on any of the hard drives that are connected to the computer.
This tool doesn't have a graphical interface, making it necessary to perform all the tasks from a command line terminal.
Monitor the health of your hard drives thanks to Smartmontools.
