apt-get install smartmontools
使用如下命令查看硬盘挂载在哪个目录下 df -h
比如说硬盘挂载在/dev/sda1, 那就使用如下命令查看“” smartctl --all /dev/sda1
假设结果如下:
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.

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 === ... SMART support is: Available - device has SMART capability. SMART support is: Enabled Temperature Warning: Disabled or Not Supported
=== START OF READ SMART DATA SECTION === SMART Health Status: OK Current Drive Temperature: 0 C Drive Trip Temperature: 0 C
Error Counter logging not supported
那么使用如下命令可以解决问题: smartctl -d sat --all /dev/sda1
输出结果如下:
