Case Study 2: Corrupted 64GB SD Card

• Issue: SD card showed "in use" error due to file system corruption.
• Procedure:
  1. Imaged the SD card to preserve data.
  2. Reconstructed file system on the image and extracted key documents and videos.
  3. Reformatted original card after confirming successful recovery.
• Expected Results: Key data intact; SD card reusable.
• Precautions: Avoided writing new files before recovery.
