Gutmann Wipe Method & NDW: A Comprehensive Data Erasure Solution
The Gutmann Wipe Method is an algorithm developed by Peter Gutmann and Colin Plumb in 1996 for securely erasing the contents of computer hard disk drives.
This method is considered one of the most secure data erasure protocols available, as it overwrites the disk's data with pseudo-random values 35 times.
The Gutmann Wipe Method is particularly useful for protecting sensitive data and ensuring that it cannot be recovered by unauthorized individuals or organizations.

Peter Gutmann, is a data wiping technique designed to securely erase data from storage devices, particularly hard drives. This method is known for its thoroughness, involving 35 passes of data overwriting, each with a specific pattern.
For most users and organizations today, following established data wiping standards recommended by government agencies like the U.S. Department of Defense or using reliable data erasure software is sufficient for ensuring data security. These methods are more efficient and effective than the extensive 35-pass Gutmann approach.
How the Gutmann Wipe Method Works
The Gutmann Wipe Method involves multiple passes of data overwriting to ensure the complete destruction of the original disk contents. The first and last four passes use random values, while passes 5 to 31 utilize a complex pattern.
This combination of random and pattern-based overwriting makes it extremely difficult, if not impossible, to recover the original data from the wiped disk.
Benefits of the Gutmann Wipe Method
- High Security: The Gutmann Wipe Method is widely recognized as one of the most secure data erasure protocols available. Its 35-pass overwriting process ensures that the original data is effectively destroyed, making it nearly impossible to recover.
- Protection for Sensitive Data: The Gutmann Wipe Method is particularly useful for erasing sensitive data, such as financial records, personal information, or classified documents. By using this method, organizations can ensure that their data is protected from unauthorized access.
- Compliance with Data Protection Regulations: Many industries and organizations are required to comply with data protection regulations, such as the General Data Protection Regulation (GDPR) in the European Union. The Gutmann Wipe Method can help organizations meet these requirements by providing a secure and reliable data erasure solution

NDW Automated Network Data Wiping Solution & Gutman Method
Great England Software offers an Automated Network Data Wiping (NDW) solution that can assist organizations in securely erasing data using the Gutmann Wipe Method.
This software provides automated, unattended, network-based data erasure wiping, making it a convenient and efficient solution for organizations with large-scale data erasure needs. The key features of Great England Software's NDW solution include:
- Comprehensive Reporting: The NDW solution offers a web GUI reporting feature, allowing organizations to track and monitor the data erasure process. This feature can be useful for compliance purposes and internal auditing.
- Secure Network Data Erasure: The NDW solution ensures that data is securely erased from hard disk drives (HDDs) over a local area network (LAN). This method eliminates the need for manual data erasure, reducing the risk of human error and increasing efficiency.
- Certificate Generation and Label Printing: The NDW solution can generate certificates and print self-adhesive labels for the hard disk drives, providing a complete data erasure documentation process.
NDW - PXE based Network Data Wiping works out of the box, does not require any operation system on the wiping station machine, no software installation - just boot the wiping station into PXE - Network and you are already wiping data.
NDW - Hard Disk Drive Barcode Label Printing
Automatically prints the self adhesive thermal barcode labels for each data storage device upon completion of data erasure.
Automated Grading of Data Storage Devices
Each hard disk drive, NVME, SSD and other storage devices are automatically graded post data wiping.
Fully Automated, Bulk Data Erasure Certificates
Automatically generates temper proof data erasure certificates for individual as well as bulk storage devices exportable to PDF format.
Conclusion
The Gutmann Wipe Method is a highly secure data erasure protocol that can help organizations protect their sensitive data and comply with data protection regulations. Great England Software's NDW Automated Network Data Wiping solution offers a convenient and efficient way to implement the Gutmann Wipe Method for large-scale data erasure needs. For individual users and small-scale data erasure requirements, there are alternative software solutions available that support the Gutmann Wipe Method.
