SD cards are used everywhere, such as phones, cameras, drones, dash cam, and even game consoles. They're small, portable, and can store a vast amount of data. But nothing's worse than plugging in your SD card and seeing this message:
"Card not recognized" or "File is corrupted."
What Does "Corrupted" Mean?
It means the files stored on it can't be read or written correctly, which results in:
- Missing photos or videos
- Error messages
- The card becomes unreadable entirely
What Are The Common Reasons SD Cards Get Corrupted?
1. Removing the Card without Safely Removed
Removing the SD card from your device while it's still active can interrupt the file system and cause it to collapse.
Tip: Always use the "Eject" or "Unmount" option before removing the card.
2. Power Loss During Use
If your device dies while saving data to the card (such as saving, taking a photo, or transferring an image or video), the file system might collapse.
Tip: Ensure your battery is fully charged when using the SD card for important tasks.
3. Counterfeit or Fake Cards
Counterfeit SD cards are usually created from a defective SD card. They "Flash" its firmware and make it appear larger in size. It will be corrupted once the data size you saved is larger than its original size.
Tip: Buy SD cards from reputable brands and trusted stores or check the market rate before purchasing an overly cheap SD card.
4. Viruses or Malware
An infected computer can run malicious software that corrupts the File System, hide or deletes files on your hard drive.
Tip: Use antivirus software and avoid unknown or sketchy devices.
5. Too Many Write/Erase Cycles
Dashcams, security cameras, and other devices that constantly record and delete are especially likely to wear off the card's durability.
Tip: Replace your SD card when you see a message like "Scan and Fix(Recommended)."
6. Physical Damage
Water, heat, bending, or dust can physically harm the card's circuits.
Tip: Keep your card in a protective case.
What to Do if Your SD Card Gets Corrupted
Final Thoughts
SD card corruption can be frustrating, but most issues are preventable. If you do not have any important data on it, suggest getting a new SD card if it is related to wear and tear or physical damage. However, if you want to recover the data, consider seeking a professional data recovery service for assistance.
