Sometimes the USB sticks and memory cards do not allow writing by showing the message “Unable to format the drive, drive is write protected“. Or, still worse, we cannot even move, and create files on them.

In this case, since the system cannot write on the drive and can't even format it: how to solve the problem and allow the write to the media and the formatting?

The first thing I recommend to check that the USB pendrive or the memory card is not present levers on the side to enable or disable the write protection, in this case, try to change the position of the lever, and then to copy a file on the device.

If there is no lever or the change of location does not solve the problem, you have to try a software solution to force Windows to write to the drive.

The system of course is set up to never write to the drives, write-protected.

To overcome this setting, you must modify the registry.

A way to format a USB stick protected is bypass the locking system on these devices. This is done by putting the hand to the registry, to do this, open the registry editor. To open the registry editor, just use the key combination Win+R then write regedit and press on Enter.

In the editor you'll have to using the folders to the left of the interface, you must select the following path:

HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > StorageDevicePolicies

Inside you'll find the key WriteProtect: click two times and enter the value 0 (zero). As in the image below:

If you are missing the folder StorageDevicePolicies, and then the key WriteProtect to be correct, you can create it easily. Just always go in the left side of the interface and click with the right button on the folder Control in the context menu that opens, select New and then the item Key and enter the name StorageDevicePolicies.

Now go inside the new folder you created and click again with the right key and then in the context menu, click New and then click DWORD (32-bit) calls the new variable WriteProtect and let the numerical value of the initial (that is 0).

Now you can restart your PC and try to write to the USB stick or memory card or try to format the card. If everything went right you should be able to complete the task without encountering any problem or error.
