NTFS Formatter for macOS

NTFS Formatter for macOS provides a backend workflow to format NTFS volumes from a Mac, aimed at IT admins, developers, and power users who operate mixed OS storage. It enables Windows and Linux accessibility for external drives and emphasizes correctness, auditable results, and reliability over UI emphasis.
Core logic centers on input validation, safe unmounting, and controlled formatting with configurable cluster sizes, followed by optional post‑format verification. Required inputs include target_device_path, file_system_type set to NTFS, allocation_unit_size in bytes, and a perform_format flag. Optional/advanced inputs include volume_label, quick_format, verify_after_format, sector_size, and alignment.
Outputs provide a structured result containing status, final_size_bytes, and logs suitable for automated processing and audits. The system supports batch formatting scenarios and produces repeatable results across devices and sessions.
Algorithms leverage size heuristics to select a sensible default allocation_unit_size when omitted, perform a safe unmount and alignment checks, apply NTFS formatting, and optionally verify integrity post‑format. Progress is reported as percentages and a final success or error code is returned. Calculations include deriving final partition size from device capacity and chosen unit sizing.
Error handling covers invalid device paths, busy or protected devices, insufficient privileges, and read‑only volumes; in such cases the operation aborts with precise error codes and actionable logs. Industry standards for NTFS semantics and ISO timestamping are used for logs. Assumptions include admin rights and user intent to format; exclusions cover data recovery, filesystem conversions, encryption handling, and hardware defect remediation.
