Engineer Analysis

Technical inspection reveals several potential causes: corrupted partitions, unsupported file systems, damaged USB interfaces, or drive firmware issues. macOS is sensitive to file system types; drives formatted in NTFS without proper drivers may not mount. Jiwang Data Recovery engineers recommend careful diagnostics to prevent further damage and ensure most critical data remains intact during recovery. www.sosit.com.cn

Common Causes

• File System Incompatibility: NTFS or Linux-formatted drives may not mount without third-party drivers.
• Faulty USB or Cable: Broken or low-quality cables can prevent detection.
• Corrupted Partition Table: Sudden ejection or improper formatting can corrupt partition tables.
• Drive Firmware or Mechanical Failure: Malfunctions can render the drive invisible to macOS.

Recovery Procedure

1. Check cables, ports, and power supply to eliminate connection issues.
2. Connect the drive to another system (Windows/Linux) to verify accessibility.
3. Use professional recovery software capable of reading unmounted or corrupted partitions.
4. Clone the drive before performing any write operations to preserve key data.
5. Consult certified data recovery servs if mechanical or firmware issues are suspected.

Jiwang Data Recovery recommends prioritizing non-invasive diagnostics to ensure maximum recovery success.
