How to Repair a Corrupted SD Card on Mac?

I had a similar issue with my SD card on Mac, and I managed to fix it without losing any data. Here’s what you can try:

  1. Use Disk Utility: Open Disk Utility on your Mac. Select your corrupted SD card from the sidebar, then click on ‘First Aid.’ This function checks the disk for errors and attempts to repair it. It might take a bit of time, but it’s often effective.

  2. If Disk Utility doesn’t solve the problem, try a recovery tool like Disk Drill for Mac. It’s designed to recover lost files from corrupted storage devices. I’ve found it incredibly user-friendly and effective in rescuing data that seemed lost forever. Here’s a quick guide:

    • Download and install Disk Drill for Mac.
    • Insert your SD card and open the software.
    • Select the SD card from the list of available drives.
    • Click ‘Recover’ and follow the on-screen instructions.

Disk Drill has a high success rate for recovering files from corrupted SD cards, and the best part is you can preview the files before actually recovering them, which ensures you’re getting the right data back.

  1. Terminal Commands: If you’re comfortable using Terminal, you can try out some commands to repair the SD card. Here’s a simple one:

    sudo diskutil repairDisk /dev/disk2

    Replace /dev/disk2 with the actual path of your SD card, which you can find in Disk Utility under the ‘Info’ tab.

  2. Professional Help: If these methods don’t work, consider consulting a professional data recovery service. It’s a bit more expensive, but you should rely on them for critical data.

For more detailed steps on using Disk Utility’s First Aid, you can refer to the official guide here: ‘First Aid guide’.
