    What to do when you need to remove the write protection, because it is not possible to make changes to files on USB drives and SD cards? When a USB drive or SD card is write protected, files on the media cannot be edited; you can only view them. If a disk or key is write protected it is possible to read and copy files, but not write and delete files.


    The USB drive and SD cards may be write protected due to a virus or because the lock switch on the media has been enabled.



    The instructions in this article apply to Windows 10, Windows 8, and Windows 7.

    How to remove the write protection using the lock switch

    If the computer tells you that the media or card is write protected, look for a write protect switch on the card (also called a lock switch) on the USB or SD card. If your media has this switch, make sure the switch is set for writing, not just reading.

    How to remove write protection from a single file

    When you have a single file that you want to make changes to but cannot, the file may be write protected. When a file is write protected, it is marked as read only.


    1. Insert the USB drive or SD card into the appropriate port on the computer.
    2. Open Windows File Explorer.
    3. Navigate to the device and folder containing the file.
    4. Select the file
    5. Select the scheda Home, then select Property > Property
    6. In the dialog box Propertyselect Read only to remove the check mark.
    7. Select OKAY.

    5. Next to"DISKPART>,"go up "list disk“And press Submit
    6. In the list of mounted disks, find the USB drive and note the disk number. Look at the size column to locate the write protected flash drive. In this example, the computer hard drive is 29GB and the USB drive is 977MB.
    7. Enter the command "select disk disk_number “, then press Submit For example, if the unit number is 1, "select disk 1".
    8. When the disk is selected, diskpart displays a message that the disk is now the selected disk.
    9. Enter the command "attributes disk clear readonly“, Then press Submit.
    10. When the write protection has been removed from the disk, diskpart displays a message indicating that the attributes have been successfully cleared and the disk is no longer write protected.
    11. To close the diskpart window when finished, enter "go out“And press Submit.
