In their own words
Blackwire Drive Eraser & Sanitizer
Blackwire Drive Eraser & Sanitizer sanitizes supported drives for home users, technicians, repair shops, IT teams and businesses. Its methods include software overwrite, supported firmware sanitization and native NVMe Block Erase on approved connections; NVMe Cryptographic Erase is a candidate only when evidence supports it. Clear, Purge and Destroy workflows align with NIST SP 800-88 Rev.2, though the product is not certified or endorsed by NIST. Verification may use sampled or full read-back and report coverage, mismatches, errors and per-pass status. Supported interrupted overwrite jobs can resume from authenticated checkpoints after drive identity is rechecked, but verification starts over. Before raw drive access, the app requires typed confirmation and blocks the running Windows system disk and the app or Toolbox host disk. USB adapters, RAID controllers, virtual disks and unsupported connections may restrict direct firmware commands. Free is free; Home Pro is $9.99, paid once; Business is $39.99, paid once. The Windows installer and portable app require administrator privileges for direct physical-drive access.
