How to protect the removable media from being copy/write/duplication?
CD/DVD should not be copied, writeable.
I request to provide some useful information or suggest any tool to lock the media from duplication.
As soon you have access on the media file system you can copy the content. In this case the only solutions to block it it to remove the device, to disable it on BIOS/OBP level, or to restrict user level access.
