    Will not write to USB drive


    My Windows 10 OS has decided it does not like USB flash drives any more. It knows one is plugged in, there is a bleep when it's plugged in, File Manager shows it as "USB Drive H:", Device Manager shows it as a mass storage device and it is present as a hidden icon on the Desktop. So far so good, when I try to write a file to the drive I get "Please insert a disc into Drive H:". I get the same message if I try to format the drive. What's going on? It's happened with drives that I've used in the past and with brand new ones. Suggestions please.

    :)

    How To Format A Write Protected Flash Memory ?

    ¿You already tried this one?...

    Run CMD


    1. diskpart
    2. list disk

    Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

    2. select disk #
    3. clean
    4. create partition primary
    5. select partition 1
    6. active
    7. format fs=fat32
    8. assign
    9. exit

    with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

    good luck!

    Will not write to USB drive

    USB devices getting write protected

    Hi Imdad,

    Some removable storage devices like USB flash drives or pen drive have write protection which is designed to help users prevent unexpected data loss by refusing to delete or format.

    However, if you’re stuck with a write-protected USB drive that can’t be formatted. We recommend that you follow these steps on how to erase and format a write-protected USB flash drive and pen drive using the Regedit.exe tool in Windows. To do this,
    follow the steps below:

    • In the Search box, type regedit and press Enter.
    • Navigate to the following folder:

      Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

    Double-click on the WriteProtect value in the right-hand pane of Regedit.exe. Change the Value data from 1 to 0 and click OK to save the change. Close Regedit and restart your computer. Connect your USB flash drive or pen drive again, and you should find the
    write protection is removed and the device is no longer write protected.

    Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection,
    back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, refer to the following Microsoft Knowledge Base article.

    Let us know if you need further assistance.
