Expert work in HDD disks research

The study deals with the concept and history of appearance of HDD-disks, the stages of HDD-technology development. It examines the principle of their operation and illustrates the logical structure of the hard disk and the structure of the sector. Moreover, the paper describes an expert study done by means of the EncaseForensic and PC-3000 UDMA software packages, as well as the steps of the expert work with the hard disk and ways to delete information from it. Within the research we carried out a diagnostic test of the hard disk using the SMART VisionHDD program and indicated some prospects for the further development and use of such disks.
