How to Recover and Repair Damaged Documents, Photos, and Videos
1) Immediate precautions
- Stop using the affected storage device immediately.
- Work from a copy or create a full disk image (use ddrescue or manufacturer tools).
- Do repairs on the copy, never the original.
2) Recover deleted or lost files
- Use data-recovery tools (try free first): Recuva (Windows), TestDisk/PhotoRec (cross‑platform), Disk Drill, EaseUS, R‑Studio.
- Run a read-only “deep” or “full” scan; preview recovered files before saving.
- Save recovered files to a different drive.
3) Repair corrupted documents
- Microsoft Office files: try built-in repair — Word/Excel > Open > Choose file > “Open and Repair.”
- If that fails: change file extension to .zip and extract (for .docx/.xlsx), recover XML content, or use OfficeRecovery / Stellar Repair for Word/Excel.
- PDFs: try opening in different readers (Acrobat, Foxit). Use qpdf or Ghostscript to rebuild PDF structure, or specialized tools like PDF Repair Toolbox.
4) Repair corrupted photos
- For JPEG: try copy/rename, open in multiple viewers, then use JPEG-Repair Toolkit, Stellar Repair for Photo, or PixRecovery. If header is damaged, use a reference image from same camera to rebuild header.
- For RAW: use camera manufacturer recovery tools or specialized tools (JPEG-Repair, PhotoRec for recovery, or commercial RAW repair suites).
- If image opens but shows artifacts, use photo editors (Photoshop, GIMP) to salvage layers, color channels or use cloning/healing for visual fixes.
5) Repair damaged videos
- First ensure file is fully copied. Use VLC’s built-in repair for some AVI files (VLC > Preferences > Input/Codecs > repair).
- For MP4/MOV, use tools like FFmpeg (re-mux, rebuild container), Recover MP4 / fix.video / Restore.Media, or commercial tools (Stellar Repair for Video). Example FFmpeg command to remux:
Code
ffmpeg -i corrupted.mp4 -c copy repaired.mp4 - If frames are missing/truncated, try supplying a healthy reference file (same camera/codec) to advanced repair services.
6) When to image or use professionals
- If drive shows physical failure (clicking, not detected) or contains critical data, create an image if possible then contact a professional recovery lab — DIY can cause permanent loss.
7) Verification & post‑repair steps
- Verify repaired files open cleanly across multiple apps.
- Run antivirus on recovered files.
- Replace failing media and keep multiple backups (local + cloud). Use checksums (SHA-256) to detect corruption over time.
8) Quick tool summary (common choices)
- Recovery: Recuva, TestDisk/PhotoRec, Disk Drill, EaseUS, R‑Studio.
- Photo repair: JPEG-Repair Toolkit, Stellar Repair for Photo, PhotoRec (extraction).
- Video repair: FFmpeg (remux), VLC (AVI repair), fix.video / Restore.Media, Stellar Repair for Video.
- Document repair: Office built‑in “Open and Repair”, PDF toolkits, Stellar Repair for Word/Excel.
