Data Security Response
At Free Geek we take the utmost care to ensure complete data destruction of all user data that is donated to us.
Hard drives that meet our specifications for reuse are removed from their systems and wiped in our hard drive sanitation banks. The process we use is based on DOD (Department of Defense) 5220-22.M standards for data destruction and meets the requirements for NIST 800-88 guidelines. Every sector of the hard drive is overwritten 3 times using a destructive write which ensures that ALL data on the drive is completely destroyed and totally unrecoverable.
Hard drives that are below our specifications for reuse are physically destroyed on site.
If you would like to wipe your own hard drive before you come, we recommend using Darik's Boot And Nuke (DBAN): http://www.dban.org/
