Deleting files from an external hard drive on your Mac can be a necessary task to free up storage space or organize your data. Yet, at times, when you attempt this seemingly straightforward process, you hit an unexpected roadblock: you cannot delete the files successfully from an external hard drive on Mac. If so, you are not alone in facing this issue. Many Mac users have faced similar challenges. In this comprehensive and detailed guide, we'll show you how to solve the problem with 4 useful and free solutions.


Part 1. Why Cant I Delete Files from External Hard Drive on Mac


Permissions and Access Rights


One of the primary reasons you may be unable to delete files from your external hard drive is insufficient permissions or ownership settings. macOS requires appropriate permissions to modify or delete files. If the files or folders on the external hard drive are protected or restricted, you won't be able to delete them. To resolve this, you can adjust the permissions or take ownership of the files/folders.

 

File System Compatibility


Another possible reason for the inability to delete files is file system incompatibility. Different file systems have varying levels of compatibility with macOS. If your external hard drive is formatted in a file system that macOS doesn't support, such as NTFS, you may encounter issues deleting files. In such cases, you can reformat the drive to a compatible file system like exFAT or macOS Extended (Journaled).

 

Locked Files


Locked files can also prevent you from deleting them. Locked files are protected from modification or deletion to prevent accidental changes. To check if a file is locked, you can select the file, press Command + I to open the Get Info window, and ensure the "Locked" checkbox is unchecked. If the file is locked, unlock it and try deleting it again.

 

Drive Errors and Corruption


Sometimes, errors or corruption on the external hard drive can interfere with file deletion. These issues can occur due to various reasons, such as improper ejection, physical damage, or software glitches. To address this, you can use macOS's built-in Disk Utility tool to run First Aid on the external hard drive. First Aid can detect and repair common disk errors, potentially resolving the problem.

Method 3. Use Disk Utility to Delete Files from External Hard Drive


When the other methods of simply deleting files do not work or are not suitable for your use, Disk Utility can often provide a comprehensive solution, even if it is not the first choice for deleting files. The disk utility is an integral part of macOS and allows users to complete a variety of disk-related tasks from formatting and partitioning their hard drives to repairing and restoring previous versions.

 

Step 1. Go to "Launchpad" > "Utilities" > "Disk Utility".

 

Step 2. Select the drive you want to remove the files.

 

Step 3. Click "Erase" at the top menu bar. And it will pop up a window, here you should enter a new name, choose a format, and click "Security Options".

 

Step 4. Move the slider to "Most Secure" and click "OK".

 

Step 5. Click "Erase".

 

Note: Deleting files using Disk Utility can be risky because it will permanently erase all the data on the external drive. So, you should ensure that you have backed up any important data before proceeding with this method.

Method 4. Use Terminal to Delete Files from External Hard Drive


If you prefer using a command-line interface, which is more advanced but also more efficient and powerful than using the GUI, you can do the same thing by using Terminal, the command-line interface on macOS, to delete files from an external hard disk.


Step 1. Connect your external hard drive to your Mac. Go to "Launchpad" > "Utilities" > "Terminal".


Step 2. In the Terminal window, type: diskutil list.
