How to Change Permissions on External Hard Drive Mac Terminal?

Changing permissions on an external hard drive using the Mac Terminal can be a useful solution when you encounter access issues or want to control who can read, write, or execute files on your drive. The Terminal allows you to modify permissions quickly and efficiently, giving you full control over your external storage device. In this tutorial, we will guide you through the steps to change permissions on your external hard drive using the Mac Terminal.

Step 1: Launch the Terminal application on your Mac. You can find it in the Utilities folder within the Applications folder, or use the Spotlight search by pressing Command + Space and typing "Terminal."

Step 2: Connect your external hard drive to your Mac and ensure it is mounted. You can check if it is mounted by looking for its icon on the desktop or the sidebar of a Finder window.

Step 3: In the Terminal window, type the following command to navigate to the root directory of your external hard drive:

"`
cd /Volumes/YourDriveName/
"`

Replace "YourDriveName" with the actual name of your external hard drive, without any spaces.

Step 4: Once you are in the root directory of your external hard drive, you can use the "chmod" command to change the permissions. Choose the appropriate command based on what permissions you want to assign:

To give the owner read and write permissions, use:
"`
sudo chmod u+rw -R .
"`

To give the group read and write permissions, use:
"`
sudo chmod g+rw -R .
"`

To give others read and write permissions, use:
"`
sudo chmod o+rw -R .
"`

Step 5: After entering the desired command, press Enter. You will be prompted to enter your administrator password. Type it in and press Enter again. Note that while typing your password, no characters or placeholder symbols will appear on the screen.

Step 6: Terminal will change the permissions of all files and folders on your external hard drive based on the command you entered. This process may take some time, especially if you have a large amount of data on your drive.

Step 7: Once the process is complete, you can close the Terminal window and start using your external hard drive with the new permissions.

Why can’t I change permissions on external hard drive Mac?

When you are unable to change permissions on an external hard drive on your Mac, there can be several reasons behind it. Here are some possible explanations:

Compatibility Issues: It’s essential to ensure that your external hard drive is compatible with your Mac. If the hard drive is formatted in a file system that your Mac doesn’t support, it might prevent you from modifying permissions. In such cases, you may need to reformat the external hard drive to a compatible file system, such as macOS Extended (Journaled) or exFAT.

Insufficient Privileges: To modify the permissions on a file or folder, you need to have sufficient privileges. Make sure you are logged in to your Mac with an administrator account or a user account with appropriate permissions. If you’re not the owner of the files or folders on the external hard drive, you might need to take ownership or request the owner to grant you the necessary permissions.

Read-Only File System: If the external hard drive’s file system is set to read-only, it can prevent you from changing permissions. To resolve this, you can try remounting the drive with write permissions. Open the "Terminal" application and use the "mount" command along with the appropriate options to remount the drive as writable.

Damaged File System: If the file system on your external hard drive is corrupted or damaged, it might prevent you from modifying permissions. In such cases, you can attempt to repair the file system using disk utility tools available on your Mac. Open "Disk Utility," select the external hard drive, and choose the "First Aid" option to repair any issues.

Locked Files or Folders: If specific files or folders on the external hard drive are locked, you won’t be able to change their permissions. To unlock them, right-click on the file or folder, choose "Get Info," and make sure the "Locked" checkbox is unchecked. If you’re modifying permissions for multiple items, use the "Apply to enclosed items" option to propagate the changes.

Antivirus or Security Software: If you have antivirus or security software installed on your Mac, it’s possible that it’s blocking your ability to change permissions. Disable any security software temporarily and check if you can modify the permissions on the external hard drive. If the issue is resolved, you may need to configure the software to allow such modifications.

By considering these potential causes for being unable to change permissions on an external hard drive, you can troubleshoot the issue effectively and regain control over your files and folders. Remember that specific scenarios might require additional troubleshooting steps or professional assistance.
