I. How to recover lost/deleted files from SD card on Mac computer

When files are accidentally deleted from an SD card, the storage space they occupied is marked as empty, allowing new data to be written. In this case, there is still a chance to restore the deleted data. Therefore, if files are accidentally deleted from an SD card, stop using the SD card immediately to avoid new data overwriting the deleted files. Then, use data recovery software to scan and restore the data. The following introduces a practical data recovery software, Renee Undeleter, which supports both Mac and Windows systems.

Step 3: Wait for the scan, which depends on the SD card’s memory size. During scanning, double-click to preview files. If you find the file to recover, check it and click Recover to terminate the scan and start recovery. Alternatively, wait for the scan to finish, check the files to recover from the results, and click Recover.

III. Precautions for using SD card

1. When the power of the device connected to the SD card is low, try to avoid storing or deleting files, so as to avoid data loss due to sudden interruption of the reading and writing process.
2. Leave some free space on the SD card to improve device reading speed. Regularly back up files to a computer or external hard drive to ensure data retrieval if lost.
3. When not using the SD card, avoid placing it randomly to prevent staining, oxidation, damage, or moisture on the metal contacts. Store it in a special box to ensure proper use.

4. Avoid directly editing or modifying files on the SD card when connected to the computer to prevent accidental deletion or inaccessibility. Transfer the data to the computer first, then edit.
