Hi,
Does Norton redirects to Windows Defragment feature to defrag?
It looks like Defragmentation is stuck at specific point. Let's analyze and identify the cause of the issue.
We need to check if there is any corruption with the hard drive that you are using.
a. Move the mouse pointer to bottom left of the screenwhere you see preview of start menu and right-click to bring up a list of Windows settings.
b. Click on ‘Command Prompt (Admin)’ to bring up elevated command prompt.
Note: Click ‘Yes’ if it prompts for permission.
c. In the command prompt, type **‘chkdsk /r’**and press Enter.
Answer Y when ‘chkdsk’ asks you if you want to check the drive next time computer boots (restarts).
Note: While performing chkdsk on the hard drive if any bad sectors are found on the hard drive when chkdsk tries to repair that sector if any data available on that might be lost.
