Explanation

Degaussing exposes a magnetic hard drive to an extremely powerful magnetic field, permanently scrambling and destroying the magnetic domains that store data. This renders all data completely unrecoverable, even with advanced forensic tools. It is the most thorough and efficient method for bulk sanitization of HDDs. A drill or hammer physically damages the drive platters, but incomplete destruction may leave data-bearing fragments recoverable. A low-level format overwrites sectors but can sometimes still be recovered by specialized tools and also takes significantly more time for 300 drives. Degaussing is the industry-standard method for large-scale, irreversible data destruction on magnetic media.
