Securely sanitize external drives, USBs and SD cards with NIST 800-88 compliant wipes. For ultimate safety, Overwrite completely ignores your Mac's internal boot drive.
The ultimate macOS utility for forensic data destruction and compliance verification.
Overwrite is a premium, sandboxed disk sanitization tool built specifically for IT professionals, compliance officers, and security-conscious individuals who require mathematical certainty when decommissioning external media.
Whether you are wiping a stack of old USB flash drives or securely zero-filling external hard drives before disposal, Overwrite bypasses clunky terminal commands in favor of a stunning, natively designed macOS interface.
MILITARY-GRADE SANITIZATION PROTOCOLS Choose the exact level of destruction required for your security posture: • 1-Pass Zero Fill: Fast, efficient data destruction for standard wipe operations. • 3-Pass DoD 5220.22-M: The Department of Defense standard for secure erasure. • 7-Pass Gutmann Method: Maximum cryptographic destruction for extreme security environments.
INSTANT COMPLIANCE CERTIFICATES Never guess if a wipe was successful. Overwrite monitors IOKit block-level responses and instantly generates a downloadable PDF Erasure Certificate upon completion, verifying NIST SP 800-88 compliance for your institutional audit logs.
BUILT WITH ABSOLUTE SAFETY IN MIND Accidental data loss is impossible. Overwrite is explicitly programmed to ignore your Mac's internal boot drive. It strictly targets external volumes, requiring explicit user authorization via Apple's App Sandbox bridges before a single byte of data is destroyed.
CORE FEATURES: • Instantly detects and lists mounted external USBs, SD Cards, and External HDDs. • Dynamic time-remaining estimations built on real-time write speed calculation. • "Swipe to Wipe" safety locks to prevent accidental erasure clicks. • Built-in Educational Shredder UI that visualizes the overwrite process. • Beautiful dark-mode Glassmorphic interface optimized for modern macOS displays. • Native Apple Crash Reporting with zero third-party tracking SDKs.
