How To Write Data on a Read-Only MicroSD Card in Ubuntu?

Ubuntu 9

In this article, we will walk you through the process of writing data on a read-only MicroSD card in Ubuntu. This is a common issue faced by many users, and we aim to provide a comprehensive guide to address this problem.

1. Check for Physical Write Protection Switch

The first thing to verify is whether your MicroSD card or adapter has a physical write protection switch. This is a tiny switch on the side of the card or adapter that can be toggled to enable or disable write protection. Ensure that this switch is in the unlocked position before proceeding.

2. Verify File System Compatibility

The next step is to ensure that the file system on the MicroSD card is compatible with your Ubuntu operating system. You can do this by using the sudo fdisk -l command in the terminal. This command lists out all the disk partitions in your system, including their file system types.

If your MicroSD card is formatted to a file system that Ubuntu does not support for writing (like NTFS), you may need to reformat the card to a compatible file system like FAT32. Be aware that reformatting will erase all data on the card, so back up any important files first.

3. Change Permissions Using Terminal Commands

If the file system is compatible but you’re still unable to write data, you might need to change the permissions of the MicroSD card. Here are a few commands that can help:

  • gksudo nautilus: This command launches the file manager with root privileges, which should bypass any permissions issues. Once the file manager is open, navigate to the MicroSD card and try to modify the files.
  • sudo chown -hR <your username> <the SDHC drive>: This command changes the ownership of the MicroSD card to your username, allowing you to write to it. Replace <your username> with your actual username and <the SDHC drive> with the path to your MicroSD card.
  • sudo chmod -R 777 <the SDHC drive>: This command changes the permissions of the MicroSD card to allow read, write, and execute access for all users. Replace <the SDHC drive> with the path to your MicroSD card.

4. Remount the SD Card as Read-Write

If the above solutions do not work, you can try remounting the MicroSD card as read-write using the following command: sudo mount --options remount,rw <the SDHC drive>. Replace <the SDHC drive> with the path to your MicroSD card.

5. Try Using a Different Card Reader or Adapter

Sometimes, the problem might be with the card reader or adapter rather than the MicroSD card itself. If you have access to a different card reader or adapter, try using it to see if it resolves the issue.

6. Reboot the System with the SD Card Inserted

Another possible solution is to reboot your system with the MicroSD card inserted. This can sometimes resolve read-only issues.

Conclusion

If none of the above solutions work, it is possible that the MicroSD card itself is faulty or damaged. In such cases, you may need to replace the card. We hope this guide has been helpful in addressing your issue with writing data on a read-only MicroSD card in Ubuntu. Remember to always back up your data to prevent any loss during troubleshooting.
