Among the other things, we can see the status of various SMART parameters: SMART Attributes Data Structure revision number: 16 The command above produces a lot of output. Suppose we want to check the current status of the /dev/sda device we would run: $ sudo smartctl -a /dev/sda To get all the available SMART information about a storage device, we can launch the utility with the -a option (short for -all) and of course pass the path of the device we want to check as the last argument of the command. Smartctl 6.6 r4594 (local build)Ĭopyright (C) 2002-17, Bruce Allen, Christian Franke, = START OF ENABLE/DISABLE COMMANDS SECTION = What if we want to enable it? All we have to do is to run smartctl with the -s option, using “on” as argument: $ sudo smartctl -s on /dev/sda From there we can see that the device has SMART capabilities and that, in this case, SMART support is disabled. What interests us the most, however is the content of the last two lines. We can see that basic information are displayed such as the device family, model, sector sizes, etc. SMART support is: Available - device has SMART capability. SATA Version is: SATA 3.0, 6.0 Gb/s (current: 3.0 Gb/s) Sector Sizes: 512 bytes logical, 4096 bytes physicalĭevice is: In smartctl database ĪTA Version is: ACS-2 (minor revision not indicated) The output of the command is the following: = START OF INFORMATION SECTION = To perform this operation we can run the smartctl utility with the -i option (short for -info): $ sudo smartctl -i /dev/sda The first thing we want to check is if S.M.A.R.T support is active on the device. Let’s become familiar with the smartctl utility. If Archlinux is your favorite distribution, you can use pacman: $ sudo pacman -S smartmontools
