BitLocker drive encryption offers whole volume encryption. Know how to enable BitLocker whole disk encryption and effectively manage that.
Yes, BitLocker drive encryption provides whole volume encryption, but specific prerequisites must be met before enabling whole disk encryption.
▌TPM Requirement:
1. A device needs TPM 1.2 or later versions for BitLocker to utilize the system integrity check provided by TPM. If you don't know how to check and enable TPM, here's a guidance for reference.
2. If a device lacks TPM, enabling BitLocker necessitates saving a startup key on a removable drive.
▌TPM with TCG-Compliant BIOS or UEFI Firmware:
1. Devices with TPM must have a BIOS or UEFI firmware that complies with Trusted Computing Group (TCG) standards.
2. The BIOS or UEFI firmware establishes a secure preboot startup chain of trust and must support TCG-specified Static Root of Trust Measurement.
3. Computers without TPM do not require TCG-compliant firmware.
▌Operating System Drive:
Contains the OS and its support files, and it must be formatted with the NTFS file system.
▌System Drive:
1. Contains essential files for booting, decryption, and loading the operating system.
2. Must not be encrypted, and it must differ from the operating system drive.
3. On UEFI-based firmware computers, it must be formatted with the FAT32 file system. On BIOS firmware computers, it must be formatted with the NTFS file system.
4. After BitLocker is activated, it should have approximately 250 MB of free space. It is recommended to be approximately 350 MB in size. If you have insufficient disk space, you can read this passage to learn how to get more drive space.
