![]() ![]() Gutmann's methods for various old hard drives."Secure erase", a function built into modern ATA hard drives.Various methods for hard drives are described at and include ![]() Methods for flash drives and other solid-state drives are covered nicely at Jesper Mortensen's answer on SSD erasure. In conclusion, clearly documented data destruction processes supported with the right hardware can simplify an office move and keep data safe.As storage technologies change over time, using different encodings and remappings to deal with sector errors, the best way to permanently erase/wipe/shred data changes also. From there, using a shredder makes physical destruction easier, leaving scrap available for collection and proper disposal. Organizations that invest in a degausser on-site can maintain chain of custody with relative ease. However, degaussers simplify the data destruction process and increase the volume of devices that can be destroyed over time. Hard drive disposal is not as simple as hitting a hard drive with a hammer or a screwdriver. Deploy shredders to simplify physical disk destruction once data has been removed.ĭecommissioning hard disks can prove complex because of the combination of environmental and data protection standards involved.Use high-end degaussers to wipe servers and similar systems with resilient hard disks.At a minimum, companies must purchase degaussing wands.Properly destroying a hard drive is a key process during decommissioning, and degaussers are often the best option. Hard disk degaussing provides a major edge over physical destruction alone in hard drive disposal, and is the only truly effective way to wipe a hard drive when done in combination with crushing.Ī degausser will disrupt the magnetic forces of a hard disk, rendering data impossible to capture and making the drive useless. Data thieves put together and salvage information if data remains on the platons. The NSA recommends a combination of degaussing and crushing as the correct approach. Ryan Lobo steps you through effective ways to wipe a hard driveĪfter degaussing, you should consider using a product that effectively crushes the device. ![]()
