    64gb Exfat micro sd marked as dirty cant format

    Hi,

    I am unsure of where this belongs. But the sd card in my phone has been dirty, and i am unable to format it in windows. This is the 3rd card this has happpened to me and aftereach time i have completely wiped my phone and started from scratch. I have never been able to fix the card i just got them replaced by amazon. I am able to copy stuff off but nothing else.

    Any help will be greatly appreicated

    Hi

    When you say dirty, what do you mean ?

    Is it read only ? Can you check the filing system on it ?

    I had a usb pen drive that was read only and i was able to clear the read only flag using hdparm of all things.

    Kind regards

    when i run fsutil dirty query k:
    i get drive is dirty

    its file system is exfat,i use it in my s3, windows did manage to tell the probelm is a.bmp file which is corrupted and thus the entire card is read only. and the time before it was a video file i think.
