Encrypting external hard drives is essential today. It greatly lowers the risk of data breaches, unauthorized access, and not meeting important rules. Keeping your sensitive info safe should be a top goal, and encryption is a strong tool to do this.

Understanding Disk Encryption and AES Standard

Disk encryption changes data on a storage device into random noise for unauthorized users⁵. The Advanced Encryption Standard (AES) is a top encryption method, set by the US National Institute of Standards and Technology in 2001⁵. It’s a symmetric block cipher, meaning one key is used for both encrypting and decrypting data⁶.

AES uses blocks of data, from 128-bit to 256-bit, to make encryption stronger⁵. Companies use drive encryption to keep user data safe⁵. Self-encrypting drives automatically encrypt data, and file-level encryption adds more security by encrypting files⁵. To open an encrypted drive, you need an encryption key, like a fingerprint or passcode⁵.

Western Digital adds security to their devices through firmware, hardware, and making them⁵. You can set a recovery key or backup passcodes to avoid losing data forever⁵.

Encryption Algorithm	Block Size	Key Size
AES (Advanced Encryption Standard)	128-bit	128-bit, 192-bit, or 256-bit
DES (Data Encryption Standard)	64-bit	64-bit

Full disk encryption encrypts all data on a drive, old or new⁶. Now, you can encrypt your operating system files too⁶. There are two types of encryption: software, like BitLocker, and hardware, which is faster but costs more⁶.

Hardware encryption doesn’t slow down your device because it uses a separate processor⁶. Full disk encryption is key for keeping data safe, especially on work devices⁶.

The AES algorithm uses 128-bit blocks and 128, 192, or 256-bit keys, making it a symmetric cipher⁶. BitLocker and FileVault use AES with 128-bit or 256-bit keys, making them secure⁶.

Full disk encryption keeps data safe when the device is turned off⁶. But, losing the encryption key can be a big problem⁶. To stay safe, back up your data, use strong passwords, and set up remote access⁶.
