Troubleshooting SD Card Reading Issues on Mac and Sony A7 VI: A Guide to Data Recovery
If you’re a photographer or videographer, losing access to your precious images can be incredibly stressful. A common scenario involves an SD card that suddenly refuses to read on multiple devices, such as your Mac and camera. Whether due to accidental formatting or other issues, it’s important to understand your options for troubleshooting and recovering your data.
Common Causes of SD Card Recognition Problems
Several factors can lead to an SD card not being recognized:
- Accidental Formatting: Inadvertent formatting can erase the directory structure, making the card unreadable.
- Corrupted Filesystem: Errors during data transfer or improper ejecting can corrupt the card’s filesystem.
- Physical Damage: Scratches or damage to the SD card can prevent devices from reading it.
- Compatibility Issues: Using the SD card with incompatible devices or faulty adapters may cause recognition failures.
In your situation, it appears that the SD card was formatted accidentally, and now it is unreadable across multiple devices.
Troubleshooting Steps
-
Try Different Devices and Ports:
Test the SD card on various computers and card readers to rule out port issues. -
Check the Card on a Different Camera or Device:
Use another compatible device to determine if the problem is with the card or the original device. -
Use Disk Utility (Mac) or Disk Management (Windows):
On Mac, open Disk Utility (found in Applications > Utilities). - Look for the SD card in the sidebar.
- If it appears, run First Aid to repair the disk.
-
If the card does not appear, it may have severe corruption or physical issues.
-
Employ Data Recovery Software:
When the device recognizes the SD card but no files are visible, specialized software can often recover deleted or lost data. Some reputable options include: -
Recuva
- Disk Drill
- PhotoRec
-
Stellar Data Recovery

Use Dedicated SD Card Recovery Services:
If software solutions fail, professional data recovery services can often retrieve files from damaged or formatted cards, though this may involve costs.
Preventing Future Issues
