When plug in your USB flash drive, Windows will notify you if the flash drive is write protected. On some flash drive, there is a small button or a switch that can be in “locked” or “unlocked” position. If the switch is in “locked” position, you won’t be able to copy any files and do data transfers, you also won’t be able to format your drive. Even if you think you have managed to delete data, next time you plug your flash drive into the USB port, they will still be there. Despite all previously mentioned, you will still be able to view files on your thumb drive. Before doing anything, check if your USB thumb drive features such a switch and if it is into “unlocked” position. If there is no switch keep, on reading to find out other solutions.

2. Regedit

At first sight, it might feel scary and complicated, but it’s not at all. Just follow our steps, and you will get a properly working USB flash drive in no time.

  1. First, you need to run Regedit.exe. You can do so by opening start menu, clicking Run. Then type “regedit” and hit Enter. You will see The Registry Editor window.Regedit
  2. Once the Registry Editor is open, look for a folder called StorageDevicePolicies. Here is the path – HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePoliciesStorageDevicePolicies
  3. Once that’s done right click “WriteProtect” and choose “Modify..”. You can also just double click “WriteProtect.” The Edit DWORD Value window will appear.modify
  4. Next, there is such field called “Value data”. The value of this field can only be 1 or 0. “1” stands for protecting the drive with write protection and “0” stands for not to. Change it from 1 to 0 and then click OK. You’re all done! Close regedit and restart your PC. Then connect your thumb drive once again and your problem should have faded away.

3. Diskpart

If the previous step didn’t work, the next logical step is to do some work with command lines or in command prompt. You don’t have to be a programmer to work with command prompt. It’s not as hard as you might think.

  2. Type in the command prompt diskpart and press Enter. The Diskpart is a disk-partitioning tool. It’s used to change the values of your USB flash drive. When you do so, a new command line window will appear. Now type “list disk” and hit Enter. Now you should be able to see all disks on your system. Your USB flash drive should be on this list. If it’s not, make sure it’s connected and try to replug it.Diskpart
