Common Causes of Inaccessible USB Files

• Partial overwriting of deleted files before recovery.
• File system corruption (FAT32, NTFS, exFAT).
• Improper recovery software or interrupted scans.
• Physical issues in USB memory chips affecting data blocks.
• Virus or malware corrupting recovered files.

Recovery Procedure

1. Immediately stop using the USB drive to prevent further overwriting.
2. Clone the drive to ensure original data remains intact.
3. Analyze the file system using professional tools to detect logical corruption.
4. Use advanced recovery software capable of repairing corrupted headers and restoring file integrity.
5. Verify recovered files to ensure they are readable and uncorrupted.
6. Engage professional servs like Jiwang Data Recovery for complex cases or hardware issues.
