Conditions for Bitlocker:

  1. There must be at least a 350MB of space in the system drive partition. Less that will not help. Usually system partition is configured automatically. You can extend that. In order to use the automatic lock feature it is very important that the drive which has Windows 8 must also be encrypted. Remember that whatever file you will move in the partition that has encryption on the files will be automatically encrypted. And when you move the file out of from encryption partition the file will be unencrypted. It is not longer protected.
  2. To use Bitlocker your system must have a FAT32 partition. Or the latest one NTFS partition. This is a compulsory requirement for those system who boot on useful firmware. But those who are in legacy bios firmware then your system must have a NTFS file system.
  3. If you had already created a system image file or recovery partition of your system which was not encrypted before all feels are decrypted automatically when you restore.
  4. For those who are using TPM it is very important that they must turn on Bitlocker immediately once they had turned on TPM upon next boot. If you fail then there can be clash between TPM verification check and Bitlocker encryption.
  5. It is possible to use a Windows 8 bootable drive or usb to unlock a encrypted partition. IF you are using the usb to unlock the drive it is essential that usb drives must be enabled from the bios.
  6. The benefit of using Bitlocker is that when you share a encrypted file on a Windows network with others only those who have permission can access it. Other will be denied access.
