If you’re an Ubuntu user, you might have encountered a situation where you’re unable to access your hard drive via Nautilus, Ubuntu’s default file manager. This issue is often due to incorrect permissions settings. This article will guide you through the process of fixing these permissions, enabling you to regain access to your hard drive.
To fix permissions to access a hard drive in Ubuntu Nautilus, you can try changing the ownership of the drive using the chown command or modifying the permissions directly through Nautilus. If these solutions don’t work, you can run Nautilus with root privileges using the sudo nautilus command. However, always use sudo commands with caution.
Understanding Permissions in Ubuntu
In Ubuntu, permissions control the ability of users to read, write, or execute files and directories. They’re an essential part of the system’s security, ensuring that unauthorized users can’t access or modify important system files.
There are three types of permissions in Ubuntu:
- Read (r): Allows the file to be opened and read.
- Write (w): Allows the file to be modified.
- Execute (x): Allows the file to be executed as a program.
Diagnosing the Problem
Before we start fixing the problem, it’s important to understand what’s causing it. Open your terminal and navigate to the directory you’re having trouble accessing. Run the following command:
ls -lThis command will list all files and directories in the current directory, along with their permissions. If you see a - instead of an r, w, or x, it means you don’t have that permission.
Changing Ownership of the Drive
One way to fix the permissions issue is to change the ownership of the drive. This can be done using the chown command, which stands for “change owner”.
sudo chown $USER: /media/$USER/HDDIn this command, sudo gives you root privileges, chown is the command to change the owner, $USER is a variable that represents your current Ubuntu username, and /media/$USER/HDD is the location of the hard drive. Please replace HDD with the name of your hard drive.
However, this is a temporary fix. The permissions will be reset when you unplug the drive, and you’ll have to run the command again.
Modifying Permissions with Nautilus
Another solution is to modify the permissions directly through Nautilus. To do this, right-click on the folder or click on the background if you’re already inside the folder. Then go to Properties -> Permissions and select “Apply Permissions to Enclosed Files” or change the owner to “read and write”.
Using Nautilus with Root Privileges
If the above solutions don’t work, you can try running Nautilus with root privileges. This can be done using the sudo nautilus command. However, this should be used sparingly, as it can pose security risks.
Conclusion

If you’re having trouble accessing your hard drive in Nautilus, the solutions provided in this article should help resolve the issue. Always remember to use sudo commands with caution, as they give you root access and can potentially harm your system if used incorrectly.

Changing ownership of a drive allows you to have full control over the files and folders on that drive. It ensures that you have the necessary permissions to read, write, and execute files, enabling you to access and modify them as needed.
You can use the ls -l command in the terminal to list the permissions of files and directories in the current directory. The permissions will be displayed in the format of rwxrwxrwx, where the first set of three characters represents the owner’s permissions, the second set represents the group’s permissions, and the third set represents others’ permissions.
Yes, you can permanently fix the permissions issue by modifying the permissions of the drive using the chmod command. However, be cautious when changing permissions, as incorrect settings can lead to security vulnerabilities or system instability.
Running Nautilus with root privileges using the sudo nautilus command should be used sparingly and with caution. It grants you administrative access to your system, which can potentially harm your system if you make unintended changes. Use this command only when necessary and be aware of the potential risks involved.
