Unable to format Micro SD card

Solved
sunny -  
Hello, my 16GB Sandisk SD card cannot be formatted either with Windows or on my girlfriend's Mac.

The issue is that it is write-protected, but there is no security tab in the device settings.

I therefore went to the event log on my computer to see more details (see attached image) http://www.cjoint.com/c/GCDpQWGu4G4
The error is of type 5, and by researching, I confirmed that it is indeed an access limitation.
I am still an administrator on my session.

I then opened my command prompt in admin mode and here is what I did:

Nothing works; I can't format it or change anything inside. My knowledge stops here, could someone give me a hand, please?

PS: I am on Win10.

    SDs refusing to be formatted often indicate (if the selector is not set to read-only) an SD whose cells are damaged and therefore at the end of their life.

    The age of the card doesn't matter much. It's the number of read/write cycles that counts and ABOVE ALL the quality of the card.

    Nowadays, we see too many low-priced SD cards (even branded ones) and let's not kid ourselves; Low price = lower quality.

      Do you really think my micro SD card is dead?

      It doesn't seem to me that I've used it that much...

      You're probably right, but I'm still waiting to see if anyone has a solution to propose :)

      @sunny.userOtherwise, try this:

      Press the Windows key + X

      Choose Command Prompt (Admin)

      And in this command prompt in admin mode type this: 

      format /x E:


      (E: should be replaced by the letter assigned to your SD)

      You never know...

      It doesn't look good to me either...

      The /X option forces the reader to unmount before starting the formatting (just in case a program is blocking the process)

      After that, you can try temporarily disabling your antivirus or attempt formatting in safe mode, but I fear the outcome will be the same.

      @cs_PaTaTeMmmh I've heard about doing that in safe mode, F8 on reboot, right?

      Thanks for your help anyway!
