east-tec Eraser vs nwipe

east-tec Eraser is Windows software for erasing files with selectable methods, verification, and erasure reports. Listed methods include DoD 5220.22-M, GOST P50739-95, VSITR, the Bruce Schneier Algorithm, and the Peter Gutmann method. Verification provides a way to check the operation, while reports provide a record of the erasure. The Eraser Plan costs $39.95 a year, billed per year, and includes one year of free updates and support. A 15-day trial is available, but there is no free plan. The product is therefore a paid Windows tool with an annual plan and a file-focused scope. Users can choose among the named algorithms and review the resulting verification and report information.

nwipe is a free Linux utility for securely erasing block devices, either one drive at a time or multiple disks in parallel. It runs from the command line or through an ncurses-based graphical interface. Erase methods include zero and one fills, DoD and Gutmann wipes, verification passes, and BMB21-2019. For supported drives, the GUI also offers ATA and NVMe hardware-native block erase, cryptographic scramble, and pattern overwrite. Random-pattern methods can use selectable pseudorandom generators, including AES-256-CTR and ChaCha20. I/O modes include automatic, direct, and cached; automatic mode falls back to cached I/O if direct I/O is unsupported. hdparm is required at runtime, while smartmontools and dmidecode are optional recommended tools for features such as SMART certificate data and HPA/DCO detection. nwipe can generate a three-page PDF certificate. Hardware-sanitize options are interactive in the GUI and cannot be batched with automated multi-drive commands such as autonuke. Legacy ATA Secure Erase and freeze-lock handling are not supported.
