Many factors can cause physical damage to storage media. CD-ROMs and hard disks can suffer from several mechanical failures, such as scratched surfaces or head crashes. Physical damage not only causes some data loss, but in many cases the logial structures of the file system are damaged as well. This way it gets almost impossible to find and files from different sections of hard disk.
Most physical damages cannot be repaired by end users. They generally do not have sufficient tools or required technical experience to make these amends and restore data. Hence, data recovery companies use their vast technical knowledge, important tools and utilities to restore data.
