How to remove write protection from USB or SD card?

Write protection is a security measure to avoid making changes in your removable devices like USB,SD card etc. Write protection itself defines that you can’t add files to your device or remove any of them. A write protected USB etc can only allow you to copy data from write-protected device to another but it does not permit you to delete data, paste data in it and also to rename or format the device. This method gives you more security for your files in a device, but it will only allow to copy data from it, not more than that.
