Therefore digital forensics has a bigger objective of preserving the integrity of the data that is written on the media for the court of law at the time of occurrence of the digital crime. Data Recovery and Analysis - Data Recovery and analysis is the most challenging part in the life cycle of digital forensics. Data is stored in magnetic layered media and it can be easily over written, manipulated and corrupted. Data Recovery is performed in a special lab where the hardware would be treated for recovery of raw data. Data Recovery is also the most longest and the expensive phase of Digital Forensics. Analysis of the raw data is the next phase of digital forensics. Analysis is usually done by generally running an algorithm which looks for patterns and readily available data on the raw image of the hard-disk. The data would have to be preserved for its integrity. Analysis of data is a challenging task given the condition of the data and the situation which is prevailing at the time of analysis of the data.
