    Data erasure (sometimes referred to as data clearing, data wiping, or data destruction) is a software-based method of data sanitization that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by overwriting data onto all sectors of the device in an irreversible process. By overwriting the data on ...

  5. Data remanence - Wikipedia

    en.wikipedia.org/wiki/Data_remanence

    Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...

    The general term for this problem is data remanence. In some contexts (notably the US NSA, DoD, and related organizations), "sanitization" typically refers to countering the data remanence problem. However, the retention may be a deliberate feature, in the form of an undo buffer, revision history, "trash can", backups, or the like.
