In the course of securing and gathering evidence, it is important to document each action so that the material does not lose its evidential value and can be used in court. The compatibility of gathered information with the original carrier is established based on calculated checksums, which in both cases must be compatible. Seals on cases and ports are also used. A carrier will be considered evidence only when it has not been modified following the date of its securing. For that purpose, a blocker is used, which prevents overwriting data on the carrier. All works are conducted on a copy, specially made in the computer forensics lab. Location of electronic evidence Evidence or information required may be located in various places on the computer.
