When one hard drive stores critical data, you may want to encrypt the drive to keep data safe. Both some third-party software and Windows built-in BitLocker can help perform hard drive encryption. Now, this post will show you how to encrypt hard drive in Windows 10 by using BitLocker.
Step 1: Open File Explorer. Click and select This PC. Then in the Devices and drives section, locate the hard drive partition you want to encrypt, right-click on it, and then select Turn on BitLocker from the context menu.
Step 2: After the BitLocker Drive Encryption window opens, you will choose how you want to unlock this drive, using a password or using a smart card. For convenience, put a check mark in the checkbox next to "Use a password to unlock the drive", type your passwords in the boxes (Passwords should contain uppercase and lowercase letters, numbers, spaces, and symbols), and then click Next.
Step 3: You are asked to select one option to back up the recovery key, which you can use to access your hard drive if you forget your password. For convenience, select Save to a file.
Step 4: Select one location such as Desktop and click Save, and then click Yes when prompted with a confirmation dialog to save the recovery key on your PC. Of course, for safety, you are advised to save the recovery key in a safer place such as a flash drive other than your PC.
Step 5: Once the recovery key is saved and you return to the BitLocker Drive Encryption window, click Next.
Step 6: You will be asked to select how much of your drive you want to encrypt. You can select either "Encrypt used disk space only" or "Encrypt entire drive" depending on your own needs, and then click Next.
Step 7: When you are ready to encrypt this drive, click Start encrypting.
Step 8: Wait while the encryption process is on. It will take a while depending on your computer’s performance and the space to encrypt.
Step 9: When encryption is complete, click Close.
Encryption will take effect after you restart the computer. Then you will be asked to enter the password to unlock this drive before you can access it. Even if the hard drive is moved to another computer, it's still in the encrypted state, and password is still required to access the drive.
