S.M.A.R.T. self-monitoring, analysis and reporting technology

S.M.A.R.T. is a function of modern drives that allows them to monitor themselves and, where appropriate, send an error status to the Host controller.

In Linux these functions can be controlled and the status read by using the program smartctl. With Debian apt-get can simply be used to install S.M.A.R.T.
