    Missing C drive from Defragment list


    I recently updated to Windows 10 Pro May 2019 Update version 1903. I noticed when I entered Optimise Drive, the Local Disk C was missing from the list. Any idea as to how to solve this issue?

    I re scanned the disks using Disk Management, where all the drives are visible.

    Defragment and Optimize Drives Problem

    Hi Edward,

    Based on the details you have provided, your C drive was unrecognized by the system. We suggest that you run these
    commands and see if there are any changes:


    • Open
      Command Prompt
      as
      Administrator.

    • Run
      the following commands:

      • To fix any logical file errors:

        • Chkdsk C: /f /r


      • To defrag your Drive C manually:

        • Defrag C: /D /U

    Update us on how it goes.

    Regards.

  3. Windows Defrag

    When running defrag, there is a drive listing for Windows RE Tools. It shows as a solid state drive and that it has never been defragged. It will not optimize. Clicking on it does nothing. Any suggestions?
