(FDE) Full Disk Encryption || Advantages & Disadvantages

Advantages & Disadvantages of (FDE) Full Disk Encryption

To secure the hard disk data, you can encrypt the disk. Doing (FDE) Full disk encryption is one of the best encryption methods.

Windows 10 has a built-in encrypting software called BitLocker, which can be used to encrypt a hard disk or its partition. BitLocker is free to use but if you like to you can use third-party software. Here we will talk about 3 Pros & Cons (Advantage & Disadvantage) of Full Hard Disk Encryption (FDE).

What is Full Disk Encryption (FDE)

Full Disk Encryption (FDE) means encryption at the hardware level. FDE converts the data on a hard disk into a form that cannot be understood by anyone who doesn’t have the key to “access” the conversion. Even if the hard disk is removed from its mother machine and placed in another machine, the data remains inaccessible, without the authentication key.

Full Disk Encryption (FDE) can be installed on a computing device at the time of manufacturing, or it can be installed later by any special software.

In Windows 10, Apart from Windows 10 Home version, Other versions have built-in Bit-Locker to Fully Encrypt the Hard Disk.

Full Disk Encryption (FDE) is mostly used in laptops, cause they are at high risk of theft. In a Nutshell, Full Drive Encryption protects the data a lot.

Advantage of Full Disk Encryption (FDE)

1. Strengthen Data Security

The most critical merits of FDE is it strengthened the data security. Full Disk Encryption (FDE) uses most strong encryption algorithms to secure the drives on your PCs, to protect all data stored in the drives. Even though putting the drive into other machines, data still be inaccessible without an authentication key.

2. Automatically Encrypting Data

Besides, encrypting the hard disk, Full Disk Encryption (FDE) encrypt the data as soon as it’s stored in the hard disk, The encryption process is complete automatically. This feature is much more convenient than file or folder encryption, which demands manually select a file or folder to encrypt.

3. Keep Away From Encryption Errors.

Another virtue of Full Automattic Encryption is that it can avoid encryption errors. As we all know, to some extent, user’s mistakes are inevitable. Hence, if doing encrypt drives data manually, perhaps you may make some mistakes. But FDE makes it without any errors.

Disadvantage of Full Disk Encryption (FDE)

1. Data Protection in Transit

Having great advantages, Full Disk Encryption (FDE) has also its own drawbacks. It cannot protect data while transit, if you are sharing data between devices or sent data through emails, then the data in transit is not being protected.

2. Making Computer Slow

In Full Disk Encryption (FDE), the entire disk is encrypted. Under this circumstance, every time you try to read the data or open the application, the authentication key is demanded to decrypt the disk data. This process slows down the computer, Because everything on the hard drive is encrypted, including the operating system.

3. Complicate Data Recovery

Like other kinds of encryption, a disadvantage of full disk encryption is that it complicates the data recovery. If encrypted data was able to recover with ease, then there would be no sense for encryption. Yes, it’s difficult for data recovery.


Hard Disk encryption is a technology that protects the data by strong encryption algorithms codes that cannot be deciphered easily by unauthorized people. Hard disk encryption uses encryption software or hardware to encrypt every bit of data that goes on a hard drive or its volumes.

Implementations

There are multiples tools & Softwares available in the market that allows disk encryption, but they vary in features and security. If you have some important data then you can encrypt your hard disk.

How to Encrypt Your Hard Drive in Windows 10

  1. Locate the internal drive or external drive you want to encrypt under “This PC” in Windows Explorer.
  2. Right-click on the drive and choose “Turn on BitLocker.”
  3. Choose “Enter a Password.”
  4. Enter a secure password.
  5. Choose “How to Enable Your Recovery Key” which you”ll use in case you lose your password. You can save it to different places like print it, save somewhere in your hard drive, or save the key to your Microsoft account.
  6. Click on “Encrypt Entire Drive” This option is more secure.
  7. Unless you need your drive to be compatible with older Windows machines, choose “New Encryption Mode.”
  8. Choose “Start Encrypting” to begin the encryption process. Note: this will require a restart if you’re encrypting your boot drive. Encryption will take some time, but it will run in the background, and you can still use your computer.

Note: BitLocker is not available on Windows 10 Home edition, but there is a similar feature for device encryption.

FAQ (Question & Answers)

Is doing encryption safe?

Hard Disk encryption is a technology that protects the data by strong encryption algorithms codes that cannot be deciphered easily by unauthorized people. Hard disk encryption uses encryption software or hardware to encrypt every bit of data that goes on a hard drive or its volumes. While encrypting the data you will ask to enable your recovery key, which you”ll use in case you lose your password.

What is the disadvantage of encrypting hard disk?

You’ll get three major issues after encrypting your hard drive such as:
