The FixMeTip: Checking and correcting errors on your hard drive

Over time your hard drive will experience errors and may potentially lose information. It is important to check your hard drive for errors and correct them by running a CHKDSK scan. Here’s how to do so:

Open Command Prompt

  • On Windows Vista and Windows 7: Open the Start Menu. In the search bar at the bottom type CMD and in the results that appear above right-click on Command Prompt. Select Run As Administrator.
  • On Windows 8, 8.1 and 10: Right-click on your Start Menu and then select Command Prompt (Admin)
Examples or Windows 7 (left) and Windows 10 (right)

The computer may ask you if you want to allow the following program to make changes to this PC. Click yes.

Type out chkdsk /r

In the new black window that appears, type out the following command (as shown in the picture below). To start the scan of your system files type: chkdsk /r and press enter on your keyboard.

chkdsk r

The prompt may ask you to confirm you want to run the scan. Type Y and press enter. The scan will start and correct any problems if it can, otherwise it will prompt you to restart your computer in order to run the scan. This process may take a few minutes to a few hours depending on your computer’s age and the problems (if any) it encounters.


Running a scan like this can solve issues that otherwise seem unsolvable to the average PC user. It can also save you hundreds of dollars at the computer repair shop!
