months were accidentally deleted from the course? Two computer science graduates have launched a company that can back

had countless sleepless nights to finish is the worst nightmare of all students. But if the unthinkable happens, help is at hand for a new service run by two graduates of the University of Birmingham.

Sunday Niel-Groen and Chris Elmore Datalabs Zibit created in February of this year, which specializes in recovering data from computers and storage devices. Students recently published data recovery, specialized services for students who accidentally deleted their courses.

The couple, who recently completed two degrees in computer forensics at the Faculty of the University of Technology, Engineering and Environment, use a technique called sculpture of data to retrieve the contents of files that have been deleted. It is based on a common misconception made by many: that deleting a file means that has been deleted from the hard drive

'data loss is very common, but poorly understood, "says Elmore. "When deleting a file does not mean it is actually deleted. Whether you use a Mac or Windows, your operating system keeps track of where files are stored. When you delete a file , the operating system deliberately forget that this file is found, but in fact the content is stored. "

Elmore admits that data recovery is not an exact science: "One could almost call it a black art can never say 100% that can retrieve the data, because it depends on the problem individual unit. but we have a success rate of 80-90 aa %."

data recovery is the largest companies and some universities have created their own services to address the problem of being missing. The Student Union De Montfort University in Leicestershire runs his own house on the data recovery service from March 2010, costs from £ 25, and Harvard University in the United States offers service for free to all students.
Niel Elmore and Greenland are also expanding their activities beyond data retrieval in digital forensic analysis, which involves extracting data from hard disks for the investigation of acts reprehensible and criminal. They have two cases pending at the time and hope to present their research results in the courtyard.
