Whether perfectly legal computer data has been lost through hard-drive failure or a crime has been committed, a data forensic expert has both the tools and the know-how to recover the critical data, either turning it over to its rightful owner or helping attorneys or law enforcement officers prepare their case.
In either situation, certain procedures must be followed to prevent further data loss or preserve civil or criminal evidence.
Where data has been lost due to hard-drive failure caused by fire, flood, power surge, corrupted files or accidental reformatting, follow these steps before calling a professional computer forensics company:
1. Don't run file-recovery or system-recovery software.
2. Turn off the computer, using the power button, rather than the shutdown menu.
3. Don't turn the computer back on before contacting a data forensic expert.
The data forensic company you call will evaluate the situation and explain your options.
In the case of criminal activity requiring the preservation of possibly critical computer evidence, if you are a member of law enforcement, follow proper protocol to secure the scene, restrict access to the computer, preserve fingerprint evidence and prevent loss or alteration of data from any of the computer's components. Then, either call in a computer forensics expert or secure and transport the computer to a data forensic service for analysis, using appropriate procedure.
