Pass 2 – All addressable positions are overwrite with binary ones.Pass 1 – All addressable positions are overwrite with binary zeros.The following passes conform to the US Department of Defense data erasure standard: The standard characterize the implementation of three secure overwrite passes with verification at the end of the last pass. Specifies a process for overwriting HDDs (hard disk drives) with cartridges of ones and zeros. What is the Process of The DoD 5220.22-M Data Wiping Standard? And then a random character to erase and clean the information on the storage media. It is recommended to overwrite and check all addressable locations with a character, its complement. Also, it specifies the standard procedures and necessities for sanitizing information systems that handle classified information. It is widely recognized data wiping method used by government agencies & organizations around the world to wipe drives. What Do You Mean by the DoD 5220.22-M Standard?

There are fees associated with 3-pass wipes. If the wipe fails, the hard drive will be shredded. This method is both Department of Defense 5220.22-M and NIST 800-88 compliant. 3-Pass Wipe: Software is used on hard drives to overwrite all addressable storage and indexing locations on the drive three times with zeros (0x00), complement (0xFF) and random characters and then verified.This is a standard process that is done to all reusable hard drives that we receive, free of charge. 1-Pass Wipe: Software is used on the hard drive to overwrite all addressable storage and indexing locations on the drive one time with zeros (0x00) and then verified.There are fees associated with Hard drive destruction, please email for more information regarding fees. For small batch walk-in hard drive destruction, hard drives are placed inside a specialized machine and a conical punch inside the unit delivers 12,000 pounds of hydraulic force to the drive, causing catastrophic trauma to the hard drive’s chassis, destroying its internal platter, and is then shredded. Shredding is done in our secure facility. For large batch hard drive destruction, hard drives are shredded in our industrial shredder. Hard Drive Destruction: Hard drives are destroyed according to the National Institute of Standards and Technology’s (NIST) Special Publication 800-88 Guidelines for Media Sanitization.
