我的个人博客：zhang0peter的个人博客 smartmontoolswindows系统里有很多好用的软件可以查看硬盘的总使用时长，Linux下也有类似的工具smartmontools。 S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology; often written as SMART) 现在的硬盘基本都支持SMART 对于Debian，Ubuntu系统： apt-get install smartmontools其他系统的库里也有smartmontools。 使用如下命令查看硬盘挂载在哪个目录下 df -h比如说我的硬盘挂载在/dev/sda1,使用如下命令查看。 smartctl --all /dev/sda1结果如下： smartctl 6.6 2016-05-31 r4324 [armv7l-linux-4.14.71-v7+] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Vendor: Lenovo Product: USB Hard Drive Revision: 1A Compliance: SPC-4 User Capacity: 1,000,204,886,016 bytes [1.00 TB] Logical block size: 512 bytes Serial number: 624P0LOT Device type: disk Local Time is: Tue Nov 13 10:32:38 2018 HKT SMART support is: Available - device has SMART capability. SMART support is: Disabled SMART Disabled. Use option -s with argument 'on' to enable it.发现并没有读到我们想要的信息，我们需要把SMART 打开，使用如下命令： smartctl -s on --all /dev/sda1读取成功 可以使用管道直接看到上电使用时间： smartctl -s on --all /dev/sda1 | grep Power_On_Hours结果如下： 9 Power_On_Hours 0x0032 094 094 000 Old_age Always - 2648最后一个数字2648表示用了2648小时了。 如果你读取用USB连接的移动硬盘时，很可能会出现如下错误： === START OF INFORMATION SECTION === ...
