New flash memory-based media implementations, such as solid-state drives or USB flash drives, can cause data erasure techniques to fail allowing remnant data to be recoverable. Unlike degaussing and physical destruction, which render the storage media unusable, data erasure removes all information while leaving the disk operable. Permanent data erasure goes beyond basic file deletion commands, which only remove direct pointers to the data disk sectors and make the data recovery possible with common software tools. Verify the overwriting method has been successful and removed data across the entire device.Allow for selection of a specific standard, based on unique needs, and.Ideally, software designed for data erasure should: By overwriting the data on the storage device, the data is rendered irrecoverable and achieves data sanitization. JSTOR ( November 2022) ( Learn how and when to remove this template message)ĭata erasure (sometimes referred to as data clearing, data wiping, or data destruction) is a software-based method of overwriting the data that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by using zeros and ones to overwrite data onto all sectors of the device in an irreversible process.Unsourced material may be challenged and removed.
