Personal computers including all its parts, CPU, monitor, keyboard and mouse belong to the group of "information technology and telecommunication equipment". At the present consumption rate personal computers are scrapped when they are fully or partly operating, but they do not satisfy their owners in their parameters. Operating parts, such as hard disks from personal computers, can be further used, e. g. as backup sources or by less demanding users. If it does not happen, electric and electronic waste is produced. According to the Waste Disposal Association it is necessary to support the use of waste in order to eliminate the amount of wastes determined for disposal and to preserve natural resources, particularly by reuse, recycling, composting and use of energy from wastes. Selected parts of waste hard disks from personal computers were evaluated metallographically. In addition, the used coatings were characterized and their thickness was determined. As it was found out, basic parts of hard disks are produced from basic metals, such as iron, aluminium and copper. The contents of the contribution should add to increasing knowledge and the possibilities of electrical waste recycling.
