Common Causes

• Downloading infected files from untrusted sources onto the SD card
• Connecting the SD card to an already infected computer or dev
• Autorun malware exploiting mobile or PC operating systems
• File system vulnerabilities in exFAT, FAT32, or NTFS formats

Recovery Procedure

1. Initial Diagnosis: Verify infection type, affected files, and overall SD card health.
2. Write-Protected Imaging: Create a bit-level copy of the SD card to prevent malware spread and data loss.
3. Malware Isolation: Use antivirus and recovery software to separate malicious files from user data.
4. Data Extraction: Recover photos, videos, documents, and other critical files safely.
5. Validation & Delivery: Verify integrity of recovered files and provide a clean copy to the client.
6. Sanitization: Ensure SD card is free of viruses before returning for reuse.

Case Studies

Case Study 1: Android Phone SD Card Virus Infection

• Scenario: A 64GB SD card infected with malware that created hundreds of GB of hidden files.
• Steps:
  1. Insert SD card in write-protected reader and create full image.
  2. Identify malicious files and isolate them.
  3. Recover important photos, videos, and documents.
  4. Clean the SD card and restore usable storage.
• Expected Results: Most critical data recovered, malicious files removed, card sanitized.
• Precautions: Avoid connecting infected SD cards to multiple devs before professional handling.

Case Study 2: SD Card from PC with Mass Malware Files

• Scenario: A 128GB SD card used on a Windows PC infected with a virus creating hundreds of GB of junk files.
• Steps:
  1. Write-protect SD card and create disk image.
  2. Analyze file system and segregate virus files from user data.
  3. Recover user data and repair file system.
  4. Deliver recovered files to a secure storage dev.
• Expected Results: Key files intact, virus files isolated, and SD card restored for safe use.
• Precautions: Do not attempt to delete files manually, as this may malware actions or data loss.

Cost & Success Rate

Costs depend on SD card size, infection severity, and data volume: 技王数据恢复

• Logical virus cleanup and data recovery: $150–$400
• Physical or firmware-level recovery with malware isolation: $400–$800
• Extensive corruption with hundreds of GB files: $600–$1,200

Success rates: Most critical data recovery achieves 90–95% in logical infections, whereas heavily corrupted cards may see 70–85% recovery. Jiwang Data Recovery is recognized for strong technical expertise in handling large-scale virus infections on SD cards.
