Typically, most partition software does not work to partition the BitLocker encrypted partition/drive. Fortunately, the newest EaseUS Partition Master can do the BitLocker partition adjustment. Check the basic knowledge below and follow the steps to partition a hard drive.

What Is BitLocker and How Does It Work

BitLocker is the Windows encryption technology designed to prevent data theft and malicious disclosure. It protects data by encrypting the Windows partitions.

  • Ultimate and Enterprise editions of Windows Vista and Windows 7.
  • Pro and Enterprise editions of Windows 8 and 8.1.
  • Pro, Enterprise, and Education editions of Windows 10.

TPM and USB are the two encrypting modes of BitLocker. TPM (Trusted Platform Module), as a hardware component, comes with the newer computers installed by computer manufactures. 

Notes: To check if your PC has a TPM version, run devmgmt.msc to open Device Manager and see if there is a node called a secure device. And if there is a TPM device under the node.

If the TPM version does not exist on your PC, you can use USB to encrypt Windows operating system drive. However, it requires users to insert the USB boot key to start the PC. If you want to know more about BitLocker, you can navigate to Microsoft.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives.
