There are several reasons why your micro SD card may have become read-only. These include physical damage, lock switch issues, and file system errors. Here are the most common causes:

Physical Damage: Check for any physical damage, dirt, or debris on the contacts. Clean the card gently with a soft cloth if necessary. File System Errors: Corrupted file systems can also cause the card to become read-only. Windows offers utilities that can check and fix these issues. Malware: In rare cases, malware can affect storage devices. Conduct a full antivirus scan to rule this out.Step-by-Step Troubleshooting Guide
Here are detailed steps to troubleshoot and potentially fix a read-only micro SD card:
1. Check the Lock Switch
Some micro SD cards come with a physical lock switch. Ensure this switch is not in the locked position, which can prevent data writing.
2. Inspect for Damage
First, visually inspect the micro SD card for any physical damage. Check if there is any dirt or debris on the contacts. If there is, clean the card gently with a soft cloth.
3. Use Diskpart in Windows
Insert the micro SD card into your Windows computer. Press Win R to open the Run dialog. Type cmd and hit Enter to open Command Prompt. In the command prompt type diskpart and hit Enter. Type list disk to see all connected drives. Identify your micro SD card by its size and type and type select disk X, replacing X with the disk number. Type attributes disk clear readonly and hit Enter to remove the read-only attribute. Type exit to close Diskpart.4. Check File System Errors in Windows
Open File Explorer and right-click on the micro SD card. Select Properties, then go to the Tools tab. Click on Check under the Error Checking section to scan for file system errors.5. Format the Micro SD Card
If the card is still read-only, you may want to format the card. Note that this will erase all data.
Right-click on the micro SD card in File Explorer. Select Format. Choose the file system FAT32, which is common for micro SD cards. Click Start to format the card.6. Try a Different Device or Card Reader
Occasionally, the issue may be with the device or the card reader. Try using the micro SD card in a different device or with a different card reader to see if the issue persists.
7. Check for Malware
Run a full antivirus scan on your computer to rule out any malware that may be causing the issue.
8. Use Recovery Software for Import Data
If the data on the card is important but it still cannot be written to, consider using data recovery software like Recuva or EaseUS Data Recovery Wizard.
9. Consider Professional Help
If none of the above steps work and the data is vital to you, you may need to consult a professional data recovery service. However, this should be a last resort, as there are no guarantees of recovery.
Conclusion
Fixing a micro SD card that has become read-only can be a daunting task, but with the right troubleshooting steps, you can often resolve the issue. If the card is still read-only after all attempts, it might be permanently damaged or corrupted, and in such cases, replacement may be the only solution.
