Will new data written to disk while BitLocker is encrypting the disk be encrypted? RRS feed

  • Question

  • When you enable BitLocker, there is a period of time where BitLocker is slowly encrypting the contents of the drive in the background. During this time, is it guaranteed that new data written to the disk will be encrypted as it is written? Or is it possible that it will be written to the unencrypted part of the drive, and won't be encrypted until later?

  • Hi Chris,

    Blocks that are written to the volume are encrypted before the system writes them to the physical disk. No unencrypted data is ever stored on a BitLocker-enabled volume.

  • Hi,

    Just want to clarify the below scenario.

    If I Use Full Disk Encryption and if new files are written to the disk whether the encryption for those files or data's happen again?

    If Yes. Then Can you please let me know the Difference between Full Disk Encryption and Used Space Encryption.
