The PC Inspector File Recovery
The PC Inspector File Recovery tool is a freely available tool that serves two major functions. The tool is used to recover the contents of any storage media that has attachment to a computer within the recovery process of the investigation methodology and secondly it is used to recover any deleted data from any media (Stephenson Wholesale DJ Moore Jersey , 2004). It associates unreferenced files with a conduction of either good or poor. It has the 鈥榝ind lost data鈥?feature that carries out a sector-by-sector scan that incorporates unallocated file slack and space of the storage media and it unravels any files that seems to be deleted or lost. With a good conduction on the tool, the probability of recovery of deleted or lost data is high. The most attractive advantage of this tools is that it is useful to a CFS expert and the novice computer user (EC-Council Press, 2010). It is also reliable in the recovery of all the contents from a storage media. The only disadvantage is that it is not as reliable as the encase tool in data recovery. It is also expensive.
Encase Tool
The Encase tool is a forensic tool that was developed by the Guidance Software in 1998. The functionalities of Encase include data verification, data analysis Wholesale Curtis Samuel Jersey , and disk imaging. The most important feature of this forensic tool is that it allows data recovery to take place via the inspection of unallocated space (Casey, E et al., 2002). It is also vital to note that those unallocated spaces may be containing information that is useful to an investigation. A CFS that uses Encase may start an investigation by capturing and imaging device being investigated. The tool refers to the image as 鈥淓vidence File.鈥?The file is an image of the storage device. After the Evidence file has been created, software verifies its integrity using the MD5 hash function (Fadia & Komai Wholesale Devin Funchess Jersey , 2008). If the investigation has to proceed, the tool must mount the imaged file so as to eliminate the need for restoring the captured storage. The advantage of the tool is that it enables the even non-experts to quickly review information that is in storage in the computers in real-time and it also helps to preserve metadata during triage and gathering so that the maintenance of evidence integrity is achieved (Casey et al., 2002). The tool is less expensive than as compared to the PC Inspector Recovery.

In the past, costs the costs of computer forensic experts were thousands of dollars due to the manpower that was in requirement. However, the advancement of technology being used to automate the process is helping to reduce those costs. The hourly costs of computer experts handling forensic investigations range from US$250 to US$350 and the process of investigation goes through the process of acquisition, analysis Wholesale James Bradberry Jersey , and reporting. The acquisition step normally costs around US$500. The analysis step and the reporting depend on the nature of the case being investigated. In most cases, gathering and transporting evidence can have completion within 15 hours and the total analysis costs can are less than US$5000. The certified forensic handwriting and document examiner costs $35 per hour (Committee on Identifying the Needs of the Forensic Sciences Community, & Committee on Science, Technology Wholesale Taylor Moton Jersey , and Law, 2009).
Summary of a Case Where Forensic Evidence was used
The case is concerning how the forensic evidence evidenced helped to solve Stephen Lawrence鈥檚 case. The murderers of the culprit, that is, Stephen Lawrence Wholesale Greg Olsen Jersey , were convicted in court following a case review that began in 2006. It is the scientists that were working at the LGC Forensic who found carried out the investigation using a forensic technology tool. Those scientists were known as Gary Dobson and David Norris. The scientists found hair and clothing fibers from the youth on the clothes of murderers. The main breakthrough was that the scientists discovered a microscopic speck of the victim's blood on the jacket of Jobson, one of the perpetrators.
The scientists examined the clothing that were recovered from the scene where the incident happened to find out if anything was missed and if new techniques would be helpful. The investigators found out that some cloth fragments from Lawrence鈥檚 shirt were unexpectedly transferred onto Jobson鈥檚 jacket. Then investigators then examined the samples from the original sticky tape that was recovered from the suspect鈥檚 clothes and the scientists found similar red fibers on Dobson鈥檚 jacket as well as on Norris鈥檚 sweatshirt. The scientists at LGC discovered more fibers as well as human hairs on some other tapings on the clothes of the suspects. The first sign of blood was found with the usage of the instrument known as microspectrophotometer that helped to detect the color of the fibers from Jobson鈥檚 jacket. The work of the scientists helped to a great deal to convict those perpetrators of manslaughter. The case was
