    Not able to unset Dirty Bit in Windows boot drive


    Hello, I have Windows 11 Home Single Language OS installed on my laptop. Now, when I go to Defragment and Optimize Drives tool, I am unable to Optimize my C: drive. It shows that Optimization not available. Also every time I boot up my System, it tries to repair the Drive but I don't think it is working. I have already looked up solutions for this. I have tried fsutil dirty query c: chkntfs /X c: chkdsk c: /r None of these seem to have worked. So can somebody please help me with this. Thank you.

    :)

    Dirty Bit Not Resetting

    Hi,

    I have recently noticed that every time I boot my PC it runs CHKDSK during startup. I did some research into this and I believe the cause for this is because the dirty bit is set. I checked the dirty bit status with fsutil dirty query for both my drives
    (C and D) and both came up as being dirty.

    Iv'e run chkdsk /f on both drives but the dirty bit won't go away.

    My C Drive is A Relatively New SSD

    My D Drive is A HDD

    I'm worried that there is something wrong with my drives.

    Other Weird Things:

    When I try to open 'Defragment and Optimise Drives' it doesn't open.

    When I Go Into Properties of the Disk and in Tools I Select Check for Errors, it finds errors on both drives, but when I restart to fix it it just does it's chkdsk thing again.

    PC Information:

    Intel i5-9400F

    Gigabyte H310M H 2.0

    Gigabyte RX 570

    Samsung 860 Evo 250GB SSD (Boot)

    WD Blue 1TB HDD (Storage)

    Cooler Master MWE550 v2 PSU

    Dirty Bit Not Resetting

    Hi PUFFBALL101961

    Well, that is the only method to clear a dirty bit, no point in running a full repair again, with the length of time that takes, you could just run chkdsk without any switches on your d drive, that will complete quickly, to see if that gets Windows 10 clear
    the dirty bit . .

    That seems to have completed successfully, try the following to see if it will clear the dirty bit on that drive, sometimes it can be a stubborn process to clear that . . .

    Run there one at a time

    fsutil dirty query d:

    chkntfs /x d:

    fsutil dirty query d:
