Restoring corrupted pictures from an SD card can be a challenging task, but with the right approach and tools, you can often recover your valuable images.
1. SD Card Corruption
Causes of Corruption
Physical Damage: Dropping the card or exposure to moisture can lead to damage.
Improper Ejection: Not safely removing the card from devices can corrupt files.
File System Errors: Power outages or sudden interruptions during file transfer can cause issues.
Virus Attacks: Malware can compromise the integrity of your files.
Recognizing these causes can help prevent future data loss and understand the urgency of recovery.
2. Initial Steps to Take
Stop Using the Card As soon as you notice that pictures are corrupted, stop using the SD card immediately. Writing new data can overwrite existing files, making recovery impossible.
Check the Hardware
Inspect the Card: Look for any visible damage.
Try a Different Reader: Sometimes, the card reader might be the issue. Use another reader or USB port.
Test on Another Device: See if the card works on another camera or computer to rule out device issues.
3. Using Built-in Tools

Disk Utility on Mac
Connect the SD card to your Mac.
Open "Disk Utility" from Applications > Utilities.
Select the SD card from the list.

These built-in tools can often fix minor corruption and recover access to your files.
