How To Change Owner of Root-Owned Hard Drive Partition to User in Ubuntu

Ubuntu 16

In this tutorial, we will guide you on how to change the owner of a root-owned hard drive partition to a user in Ubuntu. This can be useful in situations where you want a specific user to have full control over a partition, rather than leaving it under the control of the root user.

Quick Answer

To change the owner of a root-owned hard drive partition to a user in Ubuntu, you need to modify the /etc/fstab file by adding an entry for the partition with the desired ownership. Then, remount the partition for the changes to take effect.

Identifying the Partition

Before we can change the ownership of a partition, we first need to identify it. This can be done by checking the /etc/fstab file, which contains a list of all the partitions and their mount points.

To view the contents of this file, open a terminal and run the following command:

cat /etc/fstab

This command will display the contents of the /etc/fstab file in the terminal. Look for the partition you want to change the ownership of and note down its UUID or device name.

Modifying the /etc/fstab File

Once you’ve identified the partition, the next step is to modify the /etc/fstab file. This file is used to control how disk partitions, various other block devices, or remote filesystems are mounted into the filesystem.

To edit this file, open a terminal and run the following command:

sudo nano /etc/fstab

This command will open the /etc/fstab file in the nano text editor with root privileges.

Now, add an entry for the partition you want to change the ownership of. The entry should look something like this:

UUID=1234532123 /media/partition ntfs defaults,uid=user,gid=user 0 0

Here’s what each part of this entry means:

  • UUID=1234532123: This is the UUID of the partition. Replace 1234532123 with the actual UUID of your partition.
  • /media/partition: This is the mount point of the partition. Replace /media/partition with the actual mount point of your partition.
  • ntfs: This is the file system type of the partition. In this case, it’s NTFS, but it could be something else depending on your partition.
  • defaults,uid=user,gid=user: These are the mount options. defaults sets the default options. uid=user and gid=user set the user and group ID of the owner to user. Replace user with the actual username of the user you want to set as the owner.
  • 0 0: These are the dump and pass values. They can usually be left as 0.

After adding the entry, save the changes and exit the text editor. In nano, you can do this by pressing Ctrl+X, then Y, then Enter.

Remounting the Partition

The final step is to remount the partition so that the changes take effect. You can do this by running the following command:

sudo mount -a

This command will remount all the partitions listed in the /etc/fstab file.

Alternatively, you can reboot your system to apply the changes.

Conclusion

By following these steps, you should be able to change the owner of a root-owned hard drive partition to a user in Ubuntu. Keep in mind that changing ownership of an NTFS partition from root to a specific user may not have the same effect as changing ownership on a Linux file system. NTFS has its own permission system, and the ownership change may not be reflected in the same way. For more information on this topic, you can refer to the official Ubuntu documentation.

What is the purpose of changing the owner of a root-owned hard drive partition to a user in Ubuntu?

The purpose of changing the owner of a root-owned hard drive partition to a user in Ubuntu is to allow that specific user to have full control over the partition. This can be useful if you want to grant a user exclusive access and control over the files and directories within the partition.

How do I identify the partition I want to change the ownership of?

You can identify the partition by checking the /etc/fstab file in Ubuntu. This file lists all the partitions and their mount points. By viewing the contents of this file using the cat /etc/fstab command, you can find the partition you want to change the ownership of and note down its UUID or device name.

How do I modify the `/etc/fstab` file?

To modify the /etc/fstab file, you can use the sudo nano /etc/fstab command in the terminal. This command opens the /etc/fstab file in the nano text editor with root privileges. From there, you can add an entry for the partition you want to change the ownership of, specifying the UUID, mount point, file system type, and mount options.

How do I remount the partition after modifying the `/etc/fstab` file?

To remount the partition after modifying the /etc/fstab file, you can use the sudo mount -a command in the terminal. This command remounts all the partitions listed in the /etc/fstab file. Alternatively, you can reboot your system to apply the changes.

What should I keep in mind when changing ownership of an NTFS partition?

When changing ownership of an NTFS partition from root to a specific user, it’s important to note that NTFS has its own permission system. The ownership change may not be reflected in the same way as it would on a Linux file system. It’s recommended to refer to the official Ubuntu documentation or NTFS-specific resources for more information on the effects of changing ownership on NTFS partitions.
