Frequently Asked Questions

What is hard drive encryption, and how does it work?

Hard drive encryption is a security measure that scrambles the data stored on your hard drive, making it unreadable without a decryption key. When you encrypt your hard drive, your operating system encrypts all the data written to it, including your files, folders, and system files. This data is then stored in a scrambled format that can only be accessed with the correct decryption key.

This key is typically stored in a secure location, like your computer’s BIOS or a separate hardware token. Without the key, even if someone physically accesses your hard drive, they won’t be able to read the data. This makes it a valuable tool for protecting your sensitive information from unauthorized access.
