Computer Forensics Software
It is not so easy to extract information from a computer system without altering the existing data on it. A computer forensic expert is trained to do it and uses a wide array of Computer Forensics Software to make sure he accomplishes the task. Many tools or the software that the expert uses begin with making an exact replica of the existing data on the disk to protect its integrity before proceeding with the data hunt. The replicated data is stored as an image of the hard disk drive and is the actual subject of investigation.
