Some times, it becomes necessary to run CHKDSK in order to resolve disk errors. It is also recommended to be run once in a while to improve your system’s performance and check disk for disk errors. CHKDSK is a windows builtin utility to repair disk issues.
In this guide, we’ll be scheduling the chkdsk to be run at the reboot.
Hold the Windows Key and Press R to open Run Dialog -OR- Click the Start button and type Run and chose Run from the search results and type cmd then click OK OR type cmd in the search and select Run as administrator by right clicking it.
In the command prompt, type
chkdsk /x /f /r
After you type chkdsk /x /f /r and Hit Enter.
You will be told that “Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)” when the prompt appears hit the Y key on the keyboard and reboot your computer.
