Adding to that, the process of going through all the data is slow and costly. Forensic procedures are similar to those used in criminal investigations, often with different legal requirements and limitations. [5] The duplicate is created using a hard-drive duplicator or software imaging tools such as DCFLdd, IXimager, Guymager, TrueBack, EnCase, FTK Imager or FDAS. The original drive is then returned to secure storage to prevent tampering. The acquired image is verified by using the SHA-1 or MD5 hash functions. It is a branch of forensic science involving the process of identification, collection, preservation, examination, and presenting digital data or evidence.
