Corrupted RAW Photos? Start Here

Use this page when you know something is wrong with your RAW photos, but you do not yet know which path is right. This is the routing page for CR2, NEF, ARW, and DNG problems. Its job is to help you split three very different situations:

• the file still exists but will not open cleanly
• the file was deleted, formatted away, or lost from the card
• the storage device itself may be failing

If you choose the wrong branch too early, you can waste time or make recovery harder. Start with the split below.

1) Pick the right RAW workflow first

• The RAW file still exists, but Lightroom, Photoshop, Capture One, or Preview will not open it: use Repair Corrupted RAW Images
• The RAW file was deleted, disappeared after formatting, or the card looks empty: use Recover Deleted RAW Files
• The card, SSD, or external drive disconnects, freezes, or asks to be repaired: treat it as a storage-preservation problem first
• The same image also fails after export to JPG or TIFF: the source RAW may be damaged, but verify the storage before repeating writes

2) Use this quick symptom map

What you see	Most likely branch	Why
RAW file is present but says unsupported, cannot parse, or will not preview	RAW repair	The problem is likely inside the file
Folder is empty, card was formatted, or images were deleted	RAW recovery	You need retrieval before repair
Multiple RAW files fail together on one card	Recovery or storage triage	This is often above the single-file level
One RAW file fails, but the card and other files look normal	RAW repair	One-file corruption is the better first theory
The card disconnects or throws read errors	Storage triage	Repeated scans may worsen the situation

3) When RAW repair is the right branch

Choose RAW repair first when:

• the file size looks normal
• the RAW is still visible in Finder, Explorer, or your catalog
• only one or a few files are affected
• the storage device itself behaves normally

That workflow is about fixing damaged file structure, decoder conflicts, bad headers, or incomplete writes inside the RAW file. Use Repair Corrupted RAW Images for that branch.

4) When RAW recovery is the right branch

Choose RAW recovery first when:

• the images were deleted
• the card was formatted
• the folder disappeared
• the volume shows RAW, unallocated, or empty
• the files are trapped on unstable media

That workflow is about getting the files back from the storage device before you worry about whether each one opens perfectly. Use Recover Deleted RAW Files for that branch.

5) When the storage device is the real risk

Treat the situation as storage-first when:

• the card or drive disconnects repeatedly
• imports stall or freeze
• the device asks to be repaired or formatted
• multiple unrelated files fail together

At that point, preservation matters more than speed:

1. Stop writing new data to the device.
2. Do not save recovered files back to the same card or drive.
3. Avoid repeated import or preview attempts if the device is unstable.
4. Move to recovery or professional storage help before trying format-level repair.

6) Common RAW formats this cluster covers

This routing page applies to the formats photographers hit most often:

• Canon CR2 and CR3
• Nikon NEF
• Sony ARW
• Adobe DNG
• similar camera-native RAW variants

The exact extension matters less than the symptom. The decision is still repair, recovery, or storage triage.
