How to check the health status of disks in Linux?

In a Linux system, you can use the smartmontools tool to check the health status of your disk. Here are the steps to check your disk’s health status using smartmontools.

1. First, make sure that the smartmontools tool is installed on your Linux system. In most Linux distributions, you can install smartmontools using the following command:
2. Please install the smartmontools package using the apt-get command with superuser privileges.
3. After the installation is complete, you can use the following command to check the health status of all available disks:
4. Run the command “sudo smartctl –scan”
5. This command will display the device names of all available disks, such as /dev/sda, /dev/sdb, and so on.
6. Use the following command to view the health status of the specified disk, replacing /dev/sda with the name of the disk device you want to check.
7. Please run ‘sudo smartctl -H /dev/sda’.
8. This command will display the health status of the disk. If the status is “PASSED,” it means the disk is healthy, otherwise there may be an issue.

In addition to the commands mentioned above, smartmontools also provides other commands and options that allow you to view more detailed information about your disk, such as disk temperature, bad blocks, and more. You can use the following command to view the help documentation for smartctl:
