How to Password Protect External Hard Drives on MacBook Pro/Air

There are two methods by which you can password protect the external hard drive on Mac. Both these methods are provided in the OS itself and hence there is no need for any third-party software for securing your external hard drive.

Make sure that you select a strong password for your hard drive and jot it down somewhere so that you can access it whenever you want to unlock the hard drive.

Method 1: Disk Utility Tool

This method allows the users to create partition on the hard drive and facilitates the users to encrypt a part of the hard drive, rather than the entire drive. But it has one shortcoming: it deletes all the data present on the hard drive before encrypting it. Therefore, use this method after copying your drive data in your system.

Follow the below-mentioned steps to use this tool:
