TL;DR:

To repair inaccessible recovered photos from an SD card, immediately move the files to a healthy computer drive to prevent further corruption and use a dedicated tool like Repairit Photo Repair on copies with a normal file size.
    ● Zero-byte files or those recovering only metadata without actual image content cannot be repaired and require a deep rescan of the original storage device.
    ● Never save newly recovered or repaired photos back to the damaged SD card, as this overwrites recoverable sectors and causes permanent data loss.
    ● If thumbnails appear but full images fail to open, the preview data has survived while the main image body is damaged, which can often be fixed if the original format extension is maintained.

Recovered photos from an SD card are often inaccessible because the file headers were damaged during recovery, the photos were saved to a failing card, or the file system on the SD card is corrupted. To repair inaccessible recovered photos, first copy the files to a healthy drive, then verify format support, run photo repair, and rescan the SD card if the recovered versions are incomplete.

Follow these steps in order to reduce further corruption and improve the chance of opening or repairing the recovered photos.

Step 1
Move all recovered photos to a computer drive first. Avoid opening or editing files directly from the SD card. A failing or corrupted SD card can keep damaging files during access.
Step 2
Check whether the photos have valid file extensions and supported formats. Confirm that JPG, JPEG, PNG, HEIC, RAW, or other original formats were recovered correctly. Rename only if the extension is clearly wrong.
Step 3
Test several photos in different apps. Open the same file in the default photo viewer, another image app, and a file preview tool. Some files are readable in one app but rejected in another.
Step 4
Run photo repair on the best recovered copy. Use a dedicated photo repair tool if photos show errors, gray areas, broken thumbnails, or “invalid image” messages. Repair works best when the recovered file size is normal and most image data is still intact.
Step 5
Rescan the SD card if many repaired files still fail. Use deep scanning or signature-based recovery if the first recovery produced partial files. Save newly recovered files to another drive, not back to the SD card.

Common Issues and Fixes

Issue	Likely cause	Fix
Photos open with errors or not at all	Damaged file header during recovery.	Use image repair and compare repaired output with file size and original format.
Photos show half images, gray blocks, or lines	Incomplete sectors recovered from a corrupted SD card.	Run a deeper rescan and recover again to a different storage device.
Recovered photos are inaccessible only on one device	Unsupported codec or viewer limitation.	Test on another computer or use a different image viewer.
Files have correct names but zero size or very small size	Metadata recovered without actual image content.	Recover again with deep scan; zero-byte files usually cannot be repaired.
Fixing corrupted SD card photos keeps failing after repair	Severe data overwrite or physical SD card failure.	Stop using the card and recover remaining readable files before further degradation.

Quick Tips

These tips can help you avoid repeated corruption and identify what kind of damage you are dealing with.

RAW photos often need the original camera format to remain intact; forced conversion rarely repairs true corruption.
If thumbnails appear but full images fail, preview data may survive while the main image body is damaged.
Saving repaired files back to the same SD card can overwrite recoverable sectors.
If the SD card disconnects, becomes read-only, or shows capacity errors, file repair alone may not solve the problem.

💡Protip:

Before repairing inaccessible recovered photos, choose the most complete recovered copy first. Photo repair tools usually work better when the file size is normal and enough image data remains.
