      have you tried the above methods?
      also if your usb key is dead then you have to consider purchase a new one.

      1. Go to run, type regedit and press enter.
      2. Navigate to the path:
      If the registry key StorageDevicePolicies does not exist, you will need to create it manually.
      3. Highlight StorageDevicePolicies, and then create a New DWORD (32-bit) Value named as WriteProtect.
      4. Double click the key WriteProtect in the right window and set the value to 0 in the Value Data Box and press OK button
      5. Restart your computer and see if this help

      1. Start > search bar -> CMD and press enter
      2. type< diskpart
      3. type< list disk
      4. type< select disk # (# is the number of the USB key)
      5. type< attributes disk clear readonly

      For a Transcend drive, go here to use their online recovery tool. I have heard that it also works with Corsair devices but have not tested it myself.

    This method will work only ,if any Linux OS is installed in your PC (I used Ubuntu).Just start Linux OS.Plug your Pen drive.Open your Pen drive by the system.You will find the files which are affected by Virus which are some time invisible in Windows.Just delete all the files(Right click on the file -> Move to trash).That is enough.(If it is not working,Can't delete,do it again by removing and connecting you pen drive to PC).
    I Fount this method because,none of the solutions which I got from the Internet didn't worked.
    I wish this will work.

      I'm sorry that none of the solutions above worked for you. Unfortunately, I don't know the answer either. Maybe you should try to ask a new question via the respective button on MakeUseOf Answers.

    Some flash drives have a little switch on them somewhere that enables write protect. Might check to see if it has one, and then flick it.

    Open up a command prompt. Type "diskpart" and press enter. At the
    "DISKPART >" prompt, type "list volume". This will show you a list of
    your drives and a corresponding number. Assuming your flash drive is
    listed as "5", type "select volume 5". Then type "attributes volume
    clear readonly" and press enter.

      when i tried your post
      then i got this
      "virtual disk server error:
      the operation is not supported on removable media"
       so how to fix this

    Hello, you could try the following:

    -- click on start
    -- click on run
    -- type cmd
    -- type chkdsk and then type your drive's letter and then the switch /f. It should look like:   chkdsk (your drive's letter): /f
    -- press enter
    -- if you get any errors, click ok until chkdsk is finished

    -- remove flash drive and plug it in again

    -- try the formatting again.
