Do the following to perform chkdsk:

• Click on Windows Orb/Start button
• Now Click on Run.
• type cmd in the text field and press ENTER.
• type chkdsk and hit the enter key.
• If errors are detected, perform repair and recover readable information.
• Type chkdsk volume:/r, and press ENTER.

Note: remember this process will take lots of time. so have patience to let it complete.
