Recently we have shown you how to password protect zip files in OSX. Now we are going to take it a step further by password protecting external drives or flash drives. A lot of you might wonder why would you password protect a flash drive or an external drive. If you have sensitive information, like your social security number, bank accounts, or even passwords for websites, you do not want other people getting their hands on it. Especially if you misplaced your external drive. Even if it isn’t your personal information, but of your clients or friends, protecting their data with encryptions and passwords is the right thing to do. Here is how to password protect an external drive in Mac OSX.
Password Protect an External Drive in Mac OSX
On your Mac go to the Go menu and click it. From the drop down select Utilities.
Under the Utilities folder launch the Disk Utility.
The Disk Utility will open. From here you will need to select the external drive from the left pane. Then head over to the right pane and click the Erase tab. On the Erase tab change the format to “Mac OS Extended (Journaled, Encrypted)”. Underneath the Format field enter a name in the Name field. When you are ready press the Erase button at the bottom.
A prompt will appear asking you to enter in a password. Enter your password in twice, and make sure to enter a hint as well. When you are ready press the Erase button.
Disk Utility will take a few moments to erase and encrypt your external drive. When Disk Utility is finished you will be able to use your drive without entering in a password. Eject your drive and reinsert it to get the following prompt below.
Enter in your password and press the Unlock button to gain access to your drive. You can check the check box near “Remember this password in my keychain” if this is a Mac you trust.
