How to run chkdsk

After the computer is turned off unsuccessfully, which often happens due to a power outage or similar reasons, the system may errors are observed. The hard drive scan begins. This is the Chkdsk program, which tries to find and fix errors that could arise after an unexpected shutdown of the computer.

But sometimes it turns out that there are errors on the hard drive, but the check program does not start on its own, so you have to act manually.

chkdsk options

First you need to go to the “start” menu, in which you need to select “Run” (or immediately click hotkey combination Win+R). In the window that opens, you need to enter the following command: chkdsk, and you need to specify the /f parameter, in which:

/f – the parameter through which the hard drive scan begins.

The result should be something like the following command:
Chkdskc: /f

Here c can be replaced with another letter, since it may be that it is not drive c that needs to be checked, but some other one. For example, if you need to check drive d, then the command should be written as follows:
Chkdsk d: /f

Sometimes it may happen that the disk is locked for verification.
A window with the following error may appear:
"The chkdsk command cannot be executed because the specified volume is in use by another process. Should this volume be scanned the next time the system reboots?

In this case, the smartest thing to do would be to press the Y or Enter key on your keyboard. The next time the system starts, the scan program will run and try to fix errors on the hard drive. By the way, the chkdsk program has other parameters besides /f, which are used extremely rarely. They are described in the operating system reference books.
The most useful of these is /r, which is designed to find and repair bad sectors.

Command example:
Chkdsk c: /r
