The usage model is that if a device needs to be returned to the factory for repair/replacement, or is being leveraged for a new project by the customer, all potentially sensitive data needs to be securely removed prior to leaving the facility or redeployment for another project. The standards call this process 'sanitization'. The sanitization standards are different depending upon what type of media is being used. For example, the standards for magnetic disk media are different than what is required for flash memory. Seagate has a Secure Erase Utility that will perform this function for customers who need to securely erase data from a device. Data Sanitization Standards There are different levels of Sanitization specified in the standards: Clear and Purge. In most cases, the Clear level of Sanitization will suffice for most use cases, but in some cases Purge will be required. Both types of sanitization are supported by the Seagate Secure Erase Utility. The Seagate Secure Erase Utility complies with the Clear and Purge levels of Sanitization in accordance with the following Government standards: • DOD 5220.22-M - Complies with sanitization requirements for Flash EPROM (http://www.dss.mil/documents/pressroom/isl_2007_01_oct_11_2007_final_agreement.pdf) • "NIST SP800-88 - Complies with instructions for Flash EPROM (http://csrc.nist.gov/publications/nistpubs/800-88/NISTSP800-88_with-errata.pdf) The specifications state the following requirements for the two levels of Sanitization: • Clear (directly quoting from NIST and DOD publication): Perform a full chip purge as per manufacturer's data sheets • Purge (directly quoting from NIST and DOD publication): Overwrite all addressable locations with a single character, followed by performing a full chip erase as per manufacturer's data sheets.
