The value 0 removes the write protection from the registry.

Now, reboot your computer and check if the flash drive is working or not.

By any chance of you don’t see StorageDevicePolicies in the control folder then it is easy to create.

1. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control inside registry editor.

2. In the Control folder right click on the black space in the left pane. Select New -> Key and name this folder “StorageDevicePolicies”.

Just open My Computer or This PC select the flash drive and right click on it then click on Format. It may take some time to format the drive into NTFS (New file system).

If you can’t format the flash drive using Windows GUI then use the cmd to format it.

After selecting the disk type in format fs=fat32 quick and hit Enter.
