The Gutmann method, also known as the Gutmann disk method, is a technique used in the field of computer science and data security for secure data deletion. It is particularly associated with the process of overwriting data on storage media to minimize the potential for data recovery after deletion. The Gutmann method specifically involves overwriting the data on a hard drive multiple times with a predetermined pattern of binary data.
