Deleted files from an SD card remain in the sectors until new data overwrites them. Acting immediately and stopping all writes to the card is the single most important factor in recovery success.
Part 1. Stop Using the SD Card Right Now
- Remove the card from the camera or device
- Do not take more photos
- Do not copy files to the card
- Do not format the card
Every new file written to the SD card potentially overwrites a deleted file. On a 64 GB card with 4 GB of deleted RAW photos, taking just 10 new photos can overwrite several of the deleted images.
⚠️ Important: The camera may automatically write log files, thumbnails, or metadata even when you're just browsing the menu. Remove the SD card from the camera as soon as you realize files were deleted.
Part 2. Free Options for Simple Deletions
Recuva (Windows only — free, unlimited): Recuva reads FAT32 and exFAT deletion entries and recovers recently deleted files with original filenames. Best for photos deleted within the last few hours on a lightly-used card.
PhotoRec (Windows/Mac/Linux — free, unlimited): PhotoRec uses file signature scanning — recovers photos without filenames but works on more complex scenarios including formatted cards.
Part 3. Recovery Success by Scenario
| Scenario | Recovery Likelihood | Tool Recommendation |
|---|---|---|
| Just deleted, card not used since | Very high | Recuva or Ritridata |
| Deleted hours ago, some new photos taken | High | Deep scan with Ritridata |
| Quick formatted card | High | Ritridata deep scan |
| Many new photos taken since deletion | Low to moderate | Deep scan |
| Full format (overwrite) | None | — |
💡 Tip: After running recovery software, sort results by file type (JPG, CR2, NEF, MP4) before previewing. This helps you quickly find the specific photos you're looking for rather than scrolling through thousands of recovered files.
Part 4. What "Deep Scan" Means for SD Cards
Quick scan reads the file system's deletion records — fast but only finds files whose directory entries survived. Deep scan reads every sector for file signatures — slower but finds files even after format or directory corruption.
For SD cards:
- Quick scan: Good for recent simple deletion on otherwise healthy card
- Deep scan: Required for formatted cards, heavily fragmented cards, or corrupted file systems
🗣️ r/photography user after formatted wedding SD card: "Accidentally formatted an SD card with wedding photos during a ceremony. Ran recovery software with deep scan immediately after. Got back 847 of 850 photos. The 3 lost files were in the sectors used by the first shot after the format."
🗣️ r/datarecovery guidance: "For SD card recovery, preview before bulk recovering. A file that looks valid by name and size may have a corrupted first few bytes from sector overlap. Preview 10–20 files from each type before recovering the full set."
Part 5. Recover Deleted Files From SD Card With Ritridata
Ritridata recovers deleted files from SD cards on both Windows and Mac — including camera-specific algorithms for Canon, Nikon, Sony, and DJI cards for better RAW photo recovery.
Step 1 — Insert the SD card and select it from the drive list
Step 2 — Run a deep scan to find deleted files in the card sectors
Step 3 — Preview and recover files to your computer
FAQ
How long after deletion can you recover files from an SD card? There is no fixed time limit — it depends on how much the card has been used since deletion. An SD card removed immediately after deletion may yield full recovery weeks later. A card used for hundreds of new photos may have little to recover within hours.
Can I recover files deleted from an SD card in a camera? Yes — files deleted in the camera's playback mode are the same as files deleted on a computer. The deletion marker is the same, and recovery software reads the card identically regardless of where the deletion occurred.
Will recovery software work on a formatted SD card? After quick format (the camera's default), yes — the file data remains in sectors and deep scan can find it. After full format (where every sector is overwritten), recovery is not possible.
Can I recover video files from an SD card? Yes — video files (MP4, MOV, AVI) are recovered the same way as photos. Large video files are more susceptible to fragmentation — deep scan reassembles them from non-contiguous sectors.
