It is imperative that the data from storage media's are not recoverable. Sanitization of storage media refers to a process of removing data, with assurance that the data cannot be retrieved or reconstructed.
EnviroGreen Electronic Recycling uses two (3) processes depending on our Client's needs:
Process 1) DOD 5220.22-m Sanitization method, 3+ overwrite passes Pass #1 all addressable locations using binary zeros pass #2 Overwrite all addressable locations with binary ones Pass 3 & more: Overwrite all addressable locations with random bit pattern verify the final overwrite pass. Erasing a hard drive using the DoD 5220.22-M data sanitization method will prevent all software-based file recovery methods as well as hardware-based recovery methods, from recovering meaningful data from the drive.
A certificate of Destruction is available detailing the make, model, and serial number of each hard drive at a fee of $5.00 per hard drive.
Process 2) The Crusher (see video) $5 per hard drive
Process 3) Standard certificate of destruction verifying the number of hard drives destroyed $25 for certificate
