Part 2. Password Protect an External Hard Drive

If you have an external hard drive and usually use it to store important and confidential files, you should pay attention to the security of the drive. Because of the removability of external hard drives, an unprotected external drive can be accessed by anyone on any computer. It is a great potential threat to the security of the external drive as well as the data stored on it.

Is there a way to protect an external hard drive with a password and prevent it from being accessed by unauthorized users? The answer is Yes. We are going to show you how to password protect an external hard drive in Windows 10.

As you know, Windows 10 comes with a software called BitLocker pre-installed. It is designed to encrypt external hard drive devices and internal disks installed on your computer. Windows Home doesn't include BitLocker, so if that's the version you're using, we recommend upgrading to protect your data more thoroughly. 

Steps to password protect your external hard drive with BitLocker:

Step 1. Connect your external hard drive via USB, and backup your device. If you haven't already, we recommend creating a backup schedule to ensure you always have a secure, recent copy of your data.

Step 2. Open File Explorer, and identify the desired drive. Right-click to select "Turn on BitLocker".

What Does Password Protect Mean?

After protecting the files/folders on a local disk, people can read the write-protected files, but nobody can modify, delete (even shift delete), or rename them without a password. That is to say, the disk or folder is read-only, extra operations cannot be performed on the drive or the file.

When do you need to protect a drive or folder? Sometimes you need to protect your folders within a document management system, whether it's because you're concerned about sensitive data leaking to third parties or just want to keep your information private. Additionally, you only want other users to read the data on the drive without changing anything, you'll need the protection.
