HDShredder vs SecureWipe

HDShredder erases hard disks and other mass-storage contents at the physical level, independently of partition layout, file system, and operating system. It can wipe a whole drive, individual partitions, or selected areas, and supports SSDs and removable media. Each package includes a Windows program and a self-booting version with the same interface. SCSI, FireWire, and USB 3.0 are supported in Windows and in the bootable version. The Free Edition securely erases media at up to 6 GB/min and can display supported and recognized drives, though some drives require a higher edition. Standard Edition supports 15 international data-deletion standards, while Professional Edition and higher create detailed deletion reports. A pattern editor allows custom deletion procedures. Professional Edition Portable targets service providers and IT departments using arbitrary PCs, and Enterprise editions offer parallel mass deletion. Prices range from free for Free Edition to €799, paid once for Enterprise Edition 16x. Free-version users are directed to the forum; commercial-product users can open technical-support tickets.

SecureWipe is a free, open-source tool for erasing disks on Linux and Windows 10/11. It identifies HDD, SSD, and NVMe drives by model and serial number, and detects LUKS, BitLocker, and SED encryption. For encrypted drives it offers Crypto Erase first. Other methods include ANSSI Level 1 and 2, NIST Clear and Purge, and custom two-to-seven-pass wipes for HDDs. The tool blocks erasure of the system disk and disables NIST Purge for USB and other removable drives. Because overwriting is ineffective with SSD and NVMe wear-leveling, it blocks overwrite passes on those media and offers firmware-level or crypto erase options. After erasure, it checks a random sample, 10% by default, and produces a timestamped PDF certificate with drive details, method, verification result, watermark, and SHA-256 QR code, plus a raw text log. It has graphical and terminal modes, supports French and English with automatic locale detection, and requires Python 3.10 or later. The GUI also requires customtkinter. Its README identifies GPL v3 licensing and provides the software without warranty.
