nwipe
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.
