If an item is to be used in the court of law in the United States, it has to be preserved to the best of your ability. If you want to use data evidence you have to protect it as if it were a murder scene or any other type of crime scene. Most do not understand the process or the amount of data that could potentially be located in a device.
This moves us into the question “How do I preserve data evidence to be used in a court of law?” The answer we are going to talk about is a “Hardware Write Blocker”. There are more types of write blockers but we are going to look at the hardware type at this time and to be more specific we will be looking at CRU, Inc write blockers. You can see some videos of their products here VIDEOS.
