    Windows 8.1 won't optimize the C drive


    Hello. I just updated my windows 8 to 8.1 a few days ago and now when I try to optimize the C drive it just analize it and then stops. It says that the drive is 10% fragmented. In windows 8, I always optimized it without any problem. What can I do ?

    Hi Bluered and welcome to Eight Forums.

    I'd advice you to try running the "scf/ scannow" to check if there are any integrity errors that needs to be fixed.
    SFC /SCANNOW Command - Run in Windows 8

    After running this command you should try optimizing your drive again.

    Good luck.

    Need some more info....

    Such as what kind of drive? Meaning SSD or Mech?

    Raid / AHCI / IDE or what?

    Chat chipset on the motherboard or perhaps motherboard model?


    TBH seems like a driver issue.

    So what happens, i mean does it give errors or something?

    It's a mech sata drive. I have 3 partitions, tried with a different one it optimized it without problems, but when I try with the C one it just analize and then stops as if I had clicked the analize button instead the optimize one.

    You might try forcing the defragmentation. Here is a link with more information. Chose the FORCE commando. It's a site about XP, but that should not make any difference now.

    Microsoft Corporation

    Make sure you start the commandprompt as an administrator!


    Please let me know if this works.
