You accidentally formatted your SD card — or your camera insisted on formatting it before it would work. Now your photos seem gone. The good news: in most cases, formatted photos can be recovered, especially if you formatted recently and haven't taken new photos since.
Quick Format vs Full Format — Does It Matter?
When you do a quick format (the default on most cameras and Windows), only the file table is erased — the actual photo data stays untouched on the card. This means recovery is usually very successful.
A full format (also called a "low-level format") overwrites the entire card with zeros. Recovery after a full format is much harder and often impossible. Most cameras only do quick formats, so if your camera formatted the card, you're likely in the easier scenario.
How to Recover Photos from a Formatted SD Card on Mac
- Remove the SD card from your camera and connect it to your Mac via a card reader. Don't take any more photos.
- Download and install PhotoRescue — scanning and preview are free.
- Open PhotoRescue and select your SD card from the device list.
- Click "Start Scan." PhotoRescue will scan the raw sectors of the card to find deleted photo data, even after formatting.
- Preview the results. You'll see thumbnail previews of recoverable photos. For formatted cards, recovery often finds hundreds of photos.
- Select the photos you want and complete checkout. Photos are saved to your Mac's hard drive.

- Act fast. The sooner you attempt recovery after formatting, the better. Every new photo write reduces your chances.
- Don't reformat. Even if the card seems corrupted, avoid reformatting it again — it overwrites more data each time.
- Save recovered files to a different drive. Never save recovered photos back to the same SD card.
- Use a reliable card reader. Cheap card readers can cause connection issues during long scans. USB 3.0 readers are faster and more stable.
What If the Card Shows as "Unreadable"?
If macOS shows a message like "The disk you inserted was not readable by this computer," don't click Initialize (that would format the card again). Instead:
- Click Ignore.
- Open Disk Utility and check if the card appears in the sidebar (even if it won't mount).
- Open PhotoRescue — it can often read raw device data even when macOS won't mount the card.
FAQ
What are the chances of recovering photos after formatting?
After a quick format with no new photos written: typically 80–95% of photos are recoverable. After a full format or heavy use after formatting: chances drop significantly. A free scan will show you exactly what's there.
Does formatting a card multiple times make recovery harder?
Each quick format of the same card doesn't overwrite the actual photo data — it just re-erases the file table. So multiple quick formats don't significantly reduce recovery chances. However, using the card to take new photos between formats does.
Will recovered photos have their original filenames?
After formatting, the file names are usually lost. Recovered photos will be named with sequential numbers (IMG_0001, etc.). However, the photo data itself — the image and EXIF metadata like date and camera model — is typically intact.
