To address this issue, you can attempt to format the SD card to a different file system, such as FAT32 or NTFS. However, be aware that formatting will erase all data on the card. It is recommended to recover any important data before formatting.

The image below shows an error indicating that you need to format the SD card because it is RAW and cannot be recognized:

  • Virus attack.
  • Internal files become lost or corrupted.

How to Prevent This from Happening Again

Here are some general suggestions to help prevent your SD card from turning RAW again:

  • Do not interrupt the formatting process.
  • Do not eject the USB flash drive or SD card while transferring data.
  • Avoid using your SD card or USB drive on public computers to prevent virus infection.
  • Choose high-quality devices from reputable brands such as Kingston, Sandisk, Toshiba, or Samsung.
  • Keep your SD card clean: Ensure the card and its contacts are free from dust, dirt, or contaminants. Use a clean, dry cloth to gently wipe the card if needed.
  • Handle your SD card with care: Avoid removing it abruptly from devices or card readers while it’s being accessed or written to. Use the proper ejection procedures provided by your operating system.
  • Avoid exposing your SD card to extreme conditions: Protect it from extreme temperatures, humidity, and physical damage. Store it in a cool, dry place when not in use.
  • Use reliable devices and software: Opt for reputable brands for your SD card, card reader, and other devices. Be cautious with third-party software or tools that claim to recover or repair SD cards, as they may cause more harm.
  • Backup your data regularly: Regularly back up data from your SD card to another storage medium, such as a computer or cloud storage. This ensures you won't lose important files if the SD card encounters issues.
  • Scan for malware: Periodically scan your SD card for malware or viruses using reliable antivirus software. Malware can corrupt the file system and cause various issues.
