How to fix the issue of unable to change Linux hard drive to read-only mode?

If the Linux hard drive is in read-only mode and cannot be changed, there may be a few different situations and solutions available.

1. File system error: The hard drive may have entered read-only mode due to a file system error. You can try using a file system checking tool to repair the error. For example, for the ext4 file system, you can use the fsck command to repair it. Run the following command:

sudo fsck -f /dev/sdX

“/dev/sdX” is the name of your hard drive device.

1. Damaged hardware: Physical damage to the hard drive can also result in read-only mode. In this situation, it is best to back up important data and replace the hard drive.
2. The hard drive has been mounted as read-only: In some cases, the hard drive may be mounted in read-only mode. You can try remounting the hard drive as read-write mode. Run the following command:

sudo mount -o remount,rw /dev/sdX

Similarly, “/dev/sdX” is the name of your hard disk device.

1. Memory issue: In certain situations, hardware malfunctions or memory issues may cause the hard drive to enter read-only mode. It is recommended to try restarting the system to ensure that the memory and hardware devices are functioning properly. If the problem persists, further troubleshooting may be necessary.

If the above methods do not solve the problem, it is recommended to seek further assistance from the Linux community or relevant technical support.
