Smartmontools是一种硬盘检测工具,通过控制和管理硬盘的SMART(Self Monitoring Analysis and Reporting Technology,自动检测分析及报告技术)技术来实现的。
SMART技术可以对硬盘的磁头单元、盘片电机驱动系统、硬盘内部电路以及盘片表面介质材料等进行监测,当SMART监测并分析出硬盘可能出现问题时会及时向用户报警以避免计算机数据受损失。SMART技术必须在主板支持的前提下才能发生作用,而且SMART技术也不能保证能预报所有可能发生的硬盘故障。
Windows没有内置SMART相关工具,需要安装第三方工具软件,vmware虚拟机的硬盘不支持SMART,Linux上很早就支持SMART。
