Hello! It seems like you are having trouble formatting or deleting files on your memory card even though it is detected on your phone and laptop. Here are a few steps you can try to resolve this issue:
1. Check for Write Protection: Some memory cards have a physical switch that can enable or disable write protection. Ensure that this switch is in the correct position to allow you to modify the files on the memory card.
2. Use a Different Adapter: Sometimes the issue might be with the adapter you are using to connect the memory card to your computer. Try using a different card reader or adapter to see if that resolves the problem.
3. Scan for Errors: Run a disk error check on the memory card to identify and fix any issues that might be causing the problem. You can do this by right-clicking on the memory card in File Explorer, selecting Properties, going to the Tools tab, and clicking on "Check."
4. Format Using Command Prompt: If you are unable to format the memory card through the usual methods, you can try formatting it using Command Prompt. Open Command Prompt as an administrator and use the format command with the appropriate parameters for your memory card.
5. Try a Different Device: If possible, try formatting the memory card using a different device like another computer or a digital camera. This can help determine if the issue is specific to the device you are currently using.
6. Backup and Restore: Since you mentioned that you were able to back up files from the memory card, you can consider copying all the files to your computer, formatting the memory card, and then copying the files back to see if that resolves the issue.
If none of these steps work, it is possible that the memory card is corrupted or damaged. In such cases, you may need to consider replacing the memory card. Remember to always back up your important data regularly to prevent data loss in case of such issues. Let me know if you need further assistance!
