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.

    Hopefully, the anticipated major update to Windows 8.1 will fix this problem.

    BUT . . . months ago I gave up waiting for a Microsoft solution.  Purchased O&O defrag.

    I'd try this, but I don't understand it.

    After completing defrag c: -a -v from an administrative command prompt, I get the result that I should defrag the C drive, which I can't do.

    THis did not work for me, still 11% fragmented... although it ran longer and went through 7 passes.

    I have the same issue. STuck at 11% fragmented.  Microsoft wanted to charge me and said my system was out of warranty.  Just upgraded (?) my new ASUS Laptop to Windows 8.1 a month ago or so.
