|

**SMART** (Self-Monitoring, Analysis and Reporting Technology) est un protocole de diagnostic des disques durs et SSD.
|
||||
[SMART](https://fr.wikipedia.org/wiki/Self-Monitoring,_Analysis_and_Reporting_Technology) (Self-Monitoring, Analysis and Reporting Technology) est intégrée à la plupart des disques durs pour avoir des indicateurs de diagnostic. Sous Linux/Unix, [Smartmontools](https://www.smartmontools.org/) est l'outil pour exploiter la technologie SMART, notamment avec la commande `smartctl` et le démon `smartd`.
|
||||
|
||||
|
||||
## Installation
|
||||
|
||||
Sous Debian, on utilisera la commande **smartctl** fournie par le paquet **smartmontools** pour communiquer avec nos disques durs.
