The media and Maricopa County officials have been claiming that voter result databases were not deleted; and they reference the ability of the auditors to recover the deleted information as proof the voter data was never deleted. However, according to technical forensic expert Ben Cotton, the ‘D’ drive of the EMS Primary Server was in fact deleted. It was only because of his extensive experience in the data forensics field that he was able to recover the deleted files; which is exactly what he said at the Arizona State Senate hearing on May 19th.
QUESTION – ““Did you determine that the D drive was deleted?”
BEN COTTON – “I did. We follow a very strict forensics acquisition process in which we don’t turn on a system if its delivered powered off. We remove the hard drives and perform forensics imaging with write locks on to prevent any changes to those hard drives. We produce a bit for bit forensics copy of that drive. In the case of the EMS servers, there were 6 drives. 2 drives were for the operating system and they were (unintelligible) configuration. So if something was changed on the operating system drive that would automatically be reflected on both drives.”
“The other four drives were data drives and they were in a ray configuration known as 1 plus zero. So you have a volume that is mirrored but also data redundancy and striped across both drives. If I don’t turn on a system I don’t have access to the ray parameters and the county did not provide those to us. so I had to do a discovery process to determine what that ray configuration was. Part of that process is a scan across those drives to detect partitions of data and to also detect a master file table which is a record of all of the directories of the files that are contained in that partition, and a pointer to where that data resides on the hard drive. In the course of performing that discovery I found that an MFT that clearly indicated that the data base directory was deleted from that server. All of this may be moot because subsequently I have been able to recover all the deleted files and I have access to that data.”…
