Remove write protection on pen drive

Hi All,

I got the code from net :)

Here is how you can remove or uninstall write protection on pen drive. This is a common problem faced by most users. 
Often an error occurs while copying, deleting or modifying data or files for the USB. This happens because it is 'Write-Protected'. Here is a solution to the problem of the USB being write-protected. Follow the steps mentioned in this article to enable the modification, copying or deleting of files from the USB thereafter. 

Issue

This a very common problem when using USB flash drives. Sometimes when you try to copy or delete files you get an error message "Remove the write-protection or use another disk". Furthermore, it won't allow you to format it! 

Solution

To remove write protection:

• Open Start Menu >> Run, type regedit and press Enter. This will open the registry editor.
• Navigate to the following path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

• Double click the key WriteProtect in the right pane and set the value to 0
• In the Data Value Box, press OK
• Exit Registry, restart your computer and then re-connect your USB pen drive to your computer.

That is it, done. Good luck!
