Cannot defrag my computer since installing Windows 8.1?

Norton 360 says I need to optimize my C drive.

When I try  - It does not complete the process.

Remains 12% fragmented.

Any suggestions on how to fix this.

Worked fine initially when Windows 8.1 and Norton 360 was installed.

Has been a problem for about a week.

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.

Hope this information helps.

Windows 8.1 is flawed and awaiting fix.

Please fix this. We need a fix for the defragment. I tried defrag from the command prompt. It cannot defrag only the C drive (OS Partition). Other drives can be defragged. I see the following output when I defrag c drive:


Invoking defragmentation on Windows 8 (C:)...


Pre-Optimization Report:

        Volume Information:
                Volume size                 = 149.04 GB
                Free space                  = 90.69 GB
                Total fragmented space      = 2%
                Largest free space size     = 20.86 GB

        Note: File fragments larger than 64MB are not included in the fragmentation statistics.


The parameter is incorrect. (0x80070057) 


Please fix this soon.

Yours Pankaj

I recently downloaded Windows 8.1 and now I cannot defragment/optimize my hard disk/OS C:

drive. I click on Optimize and nothing happens, and my hard disk keeps getting more and more fragmented as I save stuff on my computer. How can I get my defragment/optimize to work and defragment my hard disk? Thank you.

I have the same issue. I have performed all suggested actions - but not luck. My C drive continuous to report 14% fragmentation.

The strange thing is that I used third party defragmentation software, which performed defragmentation and drive optimization reporting 0% fragmentation, BUT windows still reports 14% fragmentation! I don't understand!

Will it Defrag completely if you run it from Safe Mode, or if you try a Clean Boot?

How to perform a clean boot to troubleshoot a problem in Windows Vista, Windows 7, or Windows 8

If a program like Norton is the possible cause it may be necessary to uninstall such a program to properly test whether such a program is the cause.



Will the Defrag work if you enable the built-in Administrator and run it via that user?


This EXAMPLE (ONLY) might or might not work for you with your Defrag program it uses the built-in Administrator account to perform it?

 

"It seems that the "Run as administrator" command only gives you some administrative privileges, and they're not enough to install Java (and OpenOffice, by association). In order to get around this, you need to actually log into the built-in administrator.   Open a Command Prompt (Admin) with admin rights by  using the Windows Key + X and selecting that option.   At the prompt, type:

 

net user administrator /active:yes

 

Then log out of your regular account and back in as the built-in administrator, where you might be able to install the update.  When you're done, log back into your regular account and, for security purposes, disable the built-in administrator account using:

 

net user administrator /active:no "

I tried what was recommended and it did not work.  When I had Windows 8, I could defragment my hard drive perfectly with no problems whatsoever, but as soon as I downloaded Windows 8.1 I can no longer defragment my Hard Drive, it simply will not defragment with Windows 8.1. I do not want Windows 8.1 anymore, please tell me how I can go back to Windows 8.  Thank you.

Do any of these commands work from an Elevated Command Prompt?  See the first link for what the commands do.

Thank you for your suggestions. Unfortunately none worked!


I had, prior to your suggestion, uninstalled Norton 360 and tried defrag then but no luck.

Running defrag from the command prompt, did nothing I.e. did not even run the program.


The worst is that the disk fragmentation is climbing (went from 14% to 16%) - I guess we need a solution soon!
