As per NIST SP 800-88 Guidelines, “existing degaussers may not have sufficient force to degauss evolving magnetic storage media and should never be solely relied upon for flash memory-based storage devices or magnetic storage devices that contain non-volatile non-magnetic storage.” Cannot Sanitize Flash Storage Media: Degaussing cannot erase data from electronic chips based on FLASH NAND technology including USB flash drives, solid state drives, and flash memory cards.Some disadvantages & limitations of degaussing are as below – Disadvantages & Limitations of Degaussingĭegaussing may look simple but is risky for business, particularly if seen in the context of reliability. Further, degaussing renders the sanitized storage media unusable and leads to the generation of toxic e-waste. As a result, existing degaussers may not have sufficient force to effectively degauss such media”. However, as per NIST SP 800-88 Guidelines, “traditional techniques such as degaussing (for magnetic media) become more complicated as magnetic media evolves, because some emerging variations of magnetic recording technologies incorporate media with higher magnetic force. It involves use of a strong reverse magnetizing field generated using a degausser to neutralize the magnetic field orientation of the storage devices, thereby turning the stored data into an unreadable and irretrievable state. What is Degaussing?ĭegaussing is particularly used for sanitizing magnetic storage media such as magnetic disk, hard disk, and magnetic tapes. Let's evaluate Degaussing and Data Erasure, the two prevalent methods for sanitizing the media, and also compare their advantages and disadvantages. Though media sanitization techniques and standards may vary, the outcome is expected to be consistent- the data stored on a media should be impossible to recover by using any data recovery method or tool after the media has been sanitized. Government regulations, internal data security policies and industry standards with regard to data protection mandate the organizations to sanitize their data storage media prior to its reuse or disposal. Prevalent media sanitization methods are also devised in a way to help organization’s attain regulatory compliance with data protection laws, particularly when a storage media moves through a “secondary transaction” such as return of leased IT asset, devices refurbishment & reselling, reallocation, donation, or disposal. The primary purpose of media sanitization is to safeguard businesses & individual users from the risks of data breach & leakage. ![]() Learn how data erasure differs from degaussing and know about the limitations of degaussing in this article.ĭegaussing and Data Erasure are methods for sanitizing the data storage media such as HDD, SSD, memory cards, etc. Degaussing and data erasure are two commonly used methods for sanitizing storage devices and drives.
