Computer forensics is more than just data recovery and presentation of files in a computer.  It is more than hard drives, peripherals, and forensic software.
Computer forensics requires specialized expertise and tools that go above and beyond the normal data collection and preservation techniques available to end-users or system support personnel. Computer forensics requires expert training, the ability to think outside the box, the knowledge of investigation strategies, and the experience of how findings affect and interact in legal proceedings.
