A technique such as encryption is getting so much attention and immense positive response due to the hindrance it has created for the unwanted intrusions. Whether it is your PC, Hard drive or flash drive, all these belongings with your sensitive data could be protected through encryption and that is what makes it popular among all individuals. Hard drive encryption is a similar recommendation for you to enhance your data safety.
What is meant by Hard Drive Encryption?
Hard drive encryption is simply an implementation of regular encryption methods to a drive to enhance its protection. Through such encrypting procedure, the data stored in the hard drive is converted into a secure unreadable coded form.
Drive encrypting software makes it impossible for any unauthorized entity to access your encrypted data without the appropriate password.

These drive encryption software are divided into three main categories: software-based, hardware-based within the storage device, and hardware-based elsewhere. To achieve this level of protection on your device, you need to spend some dollars to get a high-end protection. Full disk encryption has several benefits as compared to a regular file or folder encryption or encrypted vaults.
Why You need Hard Drive Encryption?
Before you opt to encrypt the whole Drive on your system you must know how it benefits you and why you need an internal hard drive or portable hard drive encryption.
- Almost all the files on the system including the swap space and the temporary files are encrypted. This is very important because such files are prone to reveal some important and confidential data.
- When you have encrypted the whole drive then you don’t need to worry about any file or folder that is confidential and left unencrypted or you might forget some files to be encrypted etc. The Whole internal or portable hard drive encryption mechanism ensures entire drive protection with just a password or encryption key.
- If you lose your system due to any unwelcome or sudden reasons like theft or machine failure then your saved files are not accessible by anyone even after it is repaired. Therefore, even if you trash your system you don’t need to worry about the sensitive data you have stored in the system.
Methods of Drive Encryption
Internal or USB hard drive encryption can be done by various software and there are many tools in the market. Whenever a file is written and stored on the drive, it is automatically encrypted by a specialized software. However, when a file is read from the drive, the software automatically decrypts that file while rest of the data remains encrypted.
The encryption and decryption processes are same for all common applications. In many versions of Windows, for example, Windows 10 has device encryption feature enabled which runs normally in the background without letting the users even know, but it requires a specific hardware to enable and just requires an encryption password key to access the whole system and its data.
Full Hard Drive Encryption
The entire encryption of your hard drive is most appropriate and useful way to encrypt your hard drive. This method is most recommended because it protects you against an unwanted risk that could occur due to the human errors such as forgetting to encrypt a certain file.
Along with this, the complete hard drive encryption makes sure to encrypt temporary files and swipe space. That means everything on the hard drive remains safe and secure. Yet, a bit negative impact is that the full hard drive encryption makes your system processing slow. However, due to the advent of modern processors, this is not an issue anymore. Therefore, we have described the easy ways to encrypt your entire hard drive.
Encrypting Certain Files and Folders of Hard Drive
If you are unwilling to have full hard drive encryption then there is another option for encrypting certain files only. This kind of encryption might have a less impact on the performance of your system but it is a bit complicated process. While encrypting only certain files or folders on your hard drive, you need more time to figure out important data that should be protected.
However, there are few ways to encrypt certain files and folders;
- The users of Microsoft Office can encrypt and password protects the files on their system. Yet, the level of encryption become more advanced with the upgraded version of office program.
- The method of encryption is really easy on Windows using the file encrypting system. Right-click a particular folder or file you want to encrypt, click properties and then click Advanced.
- On Mac, Disk Utility could be used to encrypt single files and folders.
Lock BIOS via Password
To encrypt hard drive there is another option to lock the BIOS (basic input output system). You could implement specific settings for computer’s hardware and could even control the loading of the computer system through BIOS system.
If you secure the hard drive with a password in BIOS then the hard drive will remain locked even when the drive is entered into a new PC other than the present one. Just the password code could unlock the hard drive and it is needed every time you switch on the drive.
Hard Drive Encryption on Windows 10
Windows 10 has a complicated mechanism of encryption, like its previous versions Windows 10 doesn’t have the encryption capability in its “Core” or “Home” editions. If you need to integrate internal or portable hard drive encryption in Windows 10 you need to pay for the “Enterprise” or “Professional” versions of Windows 10 or simply use a third-party encryption solution.
Drive Encryption feature is auto-enabled by Microsoft in some of the latest Windows 10 editions which makes sure that you are login to your Windows by Microsoft account. This is because it only actually encrypts your drive if you sign into Windows with a Microsoft account. Your recovery key or password is then uploaded to Microsoft’s cloud servers. This will help you recover your data if you lose access to your PC. To check whether it is enabled on your device or not you have to perform some simple steps:
- Open the “Settings” app in Windows 10 and navigate to “System”.See the About page and look for a “Device encryption’’ setting below the window.
- If you don’t see any device encryption option, then your system doesn’t support Device Encryption feature. There are more chances that, you may not have BitLocker feature as well.So if you don’t meet either of the above-mentioned requirements then you can spend some dollars to get a third-party software to achieve drive encryption on your system.
Hard Drive Encryption by BitLocker
If your Windows version does have BitLocker as a built-in feature then you can protect your drive by the following steps:
- Go to Control Panel of Windows 7
- Choose System and Security
- BitLocker Drive Encryption
- Or just right click on the device and select Turn on BitLocker
- Setup your password to encrypt the hard drive
- Go to “Setting” app
- Select “System” option
- Go to “About” pane
- Select ‘’Bitlocker settings’’ to enable this feature.
- Select the password to encrypt your hard drive.
Portable Hard Drive Encryption
We all love to have a portable data storage device because of its convenience and portability. However, it can also be a disadvantage if we lose our external portable drive (USB flash drive) which is very common and can also be stolen easily creating immense panic among the victims.
Therefore, you should always be prepared even for the worst case and learn how to encrypt data on external and portable hard drive. You need an encryption software to encrypt files on USB flash drive. Below we have discussed some of the top encryption tools which are also used for external drive encryption.
