    The volume C was not optimized error

    The volume C was not optimized because an error was encountered: The parameter is incorrect. (0x80070057)

    I always get this error after trying to defrag and optimize my Local Disc C partition.
    It was at first stucing at pass 1, I noticed I have just few GBs space, and I free up 100GB, now it is doing many passes like 7, but at end it will show:"Needs Optimization (Fragmented 39%), precents are sometimes different.

    What does this mean?
    Is there something wrong with my hardware, software, or it is normal?

    Go to Start/Search and type diskmgmt.msc, right click the diskmgmt results and Run As Administrator. In the Elevated Disk Management window, post a screen shot of the lower pane showing your drives.
    Remember you need at least 15% of your Windows drive free to use Windows Defrag.
