nwipe vs Parted Magic

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.

Parted Magic is paid, bootable Linux software for managing storage from USB, optical disc, or PXE. It requires a 64-bit x86 processor and at least 2 GB of RAM, and supports UEFI Secure Boot, legacy BIOS, and Intel-based Mac hardware. Its tools securely erase ATA, NVMe, SAS/SCSI, and eMMC/SD drives, choosing methods according to drive capabilities. Successful erases produce signed PDF destruction certificates, with exportable cryptographically signed evidence packs. The maker says sanitization follows NIST SP 800-88 Revision 2 and technology-specific methods conform to IEEE 2883. VisParted handles MBR and GPT layouts, filesystem operations, partition moves, and conversion between MBR and GPT. Parted Magic Clone copies disks, partitions, and images while keeping the source read-only and creating verification certificates. Workflows can use local, USB, SSH, Samba, and NFS targets, plus multicast deployment with udpcast. PM Report Server receives status and evidence over a local network and can send email, webhook, or ntfy alerts. It is not an installable Windows application.
