    BitLocker: convert drive from "Used Space Only" to "Fully Encrypted"


    Hi

    Is it possible to convert a drive that is encrypted under "Used Space Only Encrypted" to be "Fully Encrypted" instead?

    I could do a full decrypt and re-encrypt, but that would take a very long time for this large drive.

    I was sure that I selected "Fully Encrypted" from the beginning, but when I check manage-bde -status the drive is listed as "Used Space Only Encrypted" so I must have missed that somehow. But I want to fix it now.

    Side note: is it possible that a drive formatted with ReFS instead of NTFS could incorrectly be reported as "Used Space Only Encrypted"?

    Thanks

    Windows 10 version: 1909

    :)

    BitLocker - Used Space Encryption on used Laptop?

    If you take a disk and set bitlocker to encrypt only used space it will encrypt the blocks used by the filesystem. If there was some old deleted stuff on the disk when you started that could in theory be recovered. After turning on bitlocker all new files are encrypted. They are not decrypted when you delete them and these deleted files can't be retrieved.

    If you have ever encrypted the whole disk you only need to encrypt used space if re-installing. It will not be possible to retrieve anything from the remaining space on the disk as it was previously encrypted.

    BitLocker - Used Space Encryption on used Laptop?

    I tried several times to encrypt the entire disk after reinstalling Windows 10 but it always took for ever (usually 10 hours) to fully encrypt my internal 320GB drive. I managed to run bitlocker successfully by encrypting only used space. My question is should I run cipher.exe /w to wipe all unused space as this is an old laptop?

    I have found manage-bde -w c: to wipe free disk and this is now working ok.

    How does Bitlocker work when only encrypting used space - i.e. if I write a file to the disk I assume it automatically encrypts it, but if I then delete that file is the space no longer encrypted and therefore open to hackers?


    Look forward to your comments.
    Thanks!
