Enter Y in the command line and the next time you restart your disk will be checked (Most often this applies to the system disk).
Thanks to this command, you can check the disk performance without installing separate programs on Windows OS and Windows Server OS.

Now let's look at which commands and distributions you can use to check the disk operation.
In order to check the hard telegram data drive, there is also no need to install any additional utilities. Everything can be done with a couple of commands on the command line.
You should familiarize yourself with the following types of commands: sudo fdisk -l and badblocks.
Sudo fdisk -l - this command allows you to find out all the disks that are connected to the system and their names.
Badblocks - this command checks the hard disk for broken sectors.
Initially, you need to enter the Sudo fdisk –l command (If that's a small letter L) and thus find out the name of your disk.
After that, you need to enter the command Badblocks -sv /dev/vda
BadBlocks
-s - Thanks to this parameter, you can track the execution of the command.
-v - This allows you to check the hard disk for broken sectors.

Also in parentheses you can see the number of errors found, the number of corrected and those that can no longer be affected.
As soon as the check is completed, you will be shown the following.
