Recover Deleted Files

description
Info Level: Intermediate Presenter: Eli the Computer Guy Length of Class: 18 Minutes Tracks Data Recovery Prerequisites Introduction to Data Recovery Purpose of Class This class teaches students how to recover files that have been deleted Topics Covered How Data is stored and deleted on hard drives Software to use to recover deleted files Class Notes Introduction Use free or inexpensive software Eli likes to use Recuva that can be downloaded at www.Recuva.com Size of Hard Drive and Data determine how long recovery will take CD's/ DVD's probably not a good idea to recover data to. Warning Stop using the computer Best to scan disk with another computer Understand How Data is Stored/ Deleted Files are not deleted, Pointers to files are deleted Once pointer has been deleted the file may, or may not be over written Securely deleted files cannot be recovered I.D.10.T Errors Be sure the file has actually been deleted
