How can I remove the write protection from pen drive?

"My USB pen drive is write protected and it happened when I copied a 3 gig size folder and the write protection stop the copying process. Whenever I let my flash drive inserted on the comp for like 5-6 mins the write protected appeared again I didn't know how I removed it but when I tried to copy a 9 gig folder the problem happened again. I can neither disable the write protection nor format the USB pen drive because it always shows the error as "The Disk is Write Protected". Is there any efficient way to remove "the Disk is Write Protected" error and format the USB pen drive?"

Possible ways to remove write protection from pen drive

Method One. Change the Pen Drive's Properties

Go to My Computer and under Devices with Removable Storage, look for your pen drive device. Right-click on it and click Properties. In the pop-up box, sometimes there's an option to Remove write-protection. Change the status of this option and try again.

Method Two. Remove write protection from pen drive using Regedit.exe

When you are facing pen drive is write protected error, it is difficult for you to erase or format the drive. But don’t worry! There is a way. You can remove the write protection, and then format a write-protected USB flash drive with no hassle. First you can check if there is a switch on your flash drive to disable the write protection. If you do not find the switch, you should remove it using Regedit.exe. Here are the steps: 

1. Plug in your pen drive to a computer.
2. Click “Start” on the taskbar to open “Run” and type in “regedit”.
3. Hit “HKEY_LOCAL_MACHINE” to expand “System”.
4. Find “Current Control Set” in “System” list to click “Control”.
5. Check whether there is a key named “Storage Device Policies” to change the digit in the “DWORD value” box into "0" and press “OK” to save the change. 

Note: if you cannot find the key named “Storage Device Policies”, you are supposed to create a one: right click “Control” to create a new key and name it as “Storage Device Policies”=> right click this new key to open “DWORD Value” and name it as “write protect”=> Double click it to change number.

After finishing all these steps, close Regedit and restart your computer. Connect your USB pen drive again, and you should find it is no longer write protected. You can now format the drive as normal by right-clicking on it in My Computer and choosing Format.
