S.M.A.R.T.，全稱為「Self-Monitoring Analysis and Reporting Technology」，即「自我監測、分析及報告技術」。是一種自動的硬碟狀態檢測與預警系統和規範。透過在硬碟硬體內的檢測指令對硬碟的硬體如磁頭、碟片、馬達、電路的執行情況進行監控、記錄並與廠商所設定的預設安全值進行比較，若監控情況將或已超出預設安全值的安全範圍，就可以透過主機的監控硬體或軟體自動向使用者作出警告並進行基本的自動修復，以提前保障硬碟資料的安全。除一些出廠時間極早的硬碟外，現在大部分硬碟的均配備該項技術。 歷史 最早期的硬碟監控技術起源於1992年IBM在為AS/400電腦的IBM9337硬碟陣列中的IBM 0662 SCSI2代硬碟機之中，後來該技術被命名為Predictive Failure Analysis（故障預警分析技術），它是透過在韌體中測量幾個重要的硬碟安全參數和評估他們的情況。從物理硬碟傳送到監控軟體的結果中被限定兩種結果：「硬碟安全」和「硬碟不久後會發生故障」。 不久，由系統製造商Compaq和硬碟製造商Seagate、Quantum和Co
