| 释义 | secure deletesecure deleteDeleting data in a storage device by overwriting the actual data with a binary pattern. For example, a normal file delete removes only the file name from the file system index while marking the data sectors available for future writes. Overwriting the sectors is a more secure way of erasing the data, and overwriting multiple times ensures that the data can never be recovered. See data remanence. |
