Data Overwriting Process for Returned Products

This statement provides Seagate customers with an overview of what happens to data on products returned to Seagate. In order to protect your privacy and other interests in data, you should delete all data, or as much as possible, prior to returning any product to Seagate. Seagate realises, however, that you may not be able to erase certain data on returned products. Seagate will always take the steps described in this statement to protect the physical security of such products and, if applicable, overwrite data as soon as possible on products recertified by Seagate.


Seagate has coordinated with the US National Security Agency (NSA) and the Center for Magnetic Recording Research (CMRR) to ensure that any products repaired by Seagate are in compliance with, or exceed, the appropriate US government specifications. Seagate repair processes follow Best Industry Practices that call for a purging of data from the media. Seagate has verified that not only does its repair process overwrite user addressable locations, but the process also overwrites the non-user accessible locations. Seagate uses random characters, high-frequency patterns and digital-zero patterns to match the drive design technologies.


The Seagate repair process ensures that all data is overwritten in a way that exceeds the appropriate US government specifications. Seagate's process of media sanitisation may be considered an advantage among those in the health industry user community (e.g. HIPAA, the US Health Insurance Portability and Accountability Act, April 2003, which enforces patient data privacy and confidentiality), the financial community, the government user community and other users who deal with sensitive data.


In addition to its process of media sanitisation, Seagate also takes steps to ensure that the collection, warehousing, shipping, testing, recertifying and scrapping of disc drives meet Seagate security standards, which generally exceed industry averages.
