What tool ensures zero data recovery after disk cleanup?

I need absolute assurance that deleted data cannot be recovered from a disk being decommissioned. Manual cleanup and formatting aren’t convincing. SysTools Data Wipe seems designed for complete data destruction using secure overwriting methods. Has anyone tested recovery attempts after using it? I’d appreciate practical feedback on its effectiveness, reliability, and suitability for scenarios where zero data recovery is non-negotiable.
