Sony A7R III SD Card Corrupted After a Shoot: What Should You Do?
Possibly, but do not keep switching recovery programs on the original card. In this r/SonyAlpha recovery case, a photographer finished a work shoot on a Sony A7R III, waited for the card activity to finish, then found the RAW card corrupted when importing to Lightroom. rcvPortable and Disk Drill did not help, and the OP later said PhotoRec could not detect the card through the USB reader.
Check the Second Card First
The A7R III can record the same still image to both card slots or split RAW and JPEG between them, depending on the Recording Mode setting. Before stressing the damaged card further, inspect the second card and copy any matching files to a safe drive.
If the Second Card Does Not Have the RAW Files, Is Software Recovery Still Worth Trying?
Only if the problem card is still detectable. Try one known-good card reader, or connect the camera to the computer with the card inserted. If the operating system sees the card with a plausible capacity and the connection stays stable, make a sector-level image first and perform further recovery attempts on that copy. DMDE, for example, supports creating a disk image and reopening that image as the source for recovery.
Choose the Next Path
- The card appears with normal capacity and stays connected: create an image before another full scan. Work from the image and save recovered RAW files to another healthy drive.
- A different reader or camera connection sees the card but it disconnects or throws read errors: stop repeated scans. Imaging may still be possible with specialist tools, but a work shoot is not a good source to experiment on.
- The card is not detected by any reader or by the camera/computer connection: ordinary recovery software has no device to scan. At that point, professional flash-memory recovery is the realistic next step.
Should You Format or Repair the Card to Make It Readable Again?
No, not before the RAW files are safe. Sony warns that formatting permanently erases data on the memory card. For this case, the goal is not to make the card usable again; it is to preserve whatever can still be read. If the card later becomes stably detectable, a readable corrupted card can still fit a logical-recovery workflow, but formatting or repair should come only after recovery.
For broader card-corruption states and the boundary between software recovery and professional service, see the damaged SD card recovery guide. For this Sony A7R III scenario, though, the next decision is simple: check the second slot, confirm whether the problem card can still be detected, and stop DIY attempts if it cannot.
