These tests were designed to verify if the same federally and state certified source
code was installed on the equipment. Auditors conducted a full forensic clone of the
drive which is a "bit-by-bit” copy. This allowed them to review deleted files, deleted
file fragments, and hidden data that may be found in slack and unallocated space.
• 20% of Election Day Tabulators (each firm tested 10%) – NO ISSUES
• 100% of Central Count Tabulators – NO ISSUES
• 100% of Election Management System work stations and servers – NO ISSUES
• 40% of Adjudication Stations (each firm tested 20%) – NO ISSUES
