Recover VMDK with Bitlocker inside

To recover data from VMDK that contains a Bitlocker encrypted disk, you need to mount it in the disk list as a disk image.

Bitlocker disks have 3 signatures that distinguish them from other file system and contain a Bitlocker Volume Master Key (VMK). VMK is required to decrypt data stored on the volume and is also encrypted with user password and recovery key. Thus to decrypt Bitlocker volume, you need Volume Master Key and user password (or recovery key).

If one of requirements are not met, my apologies, but your data is lost irrevocably.

If all the basic requirements are met, let’s continue to the recovery of Bitlocker volume in VMFS Recovery. There are two possibilities: either Bitlocker volume preserved integrity and was detected by VMFS Recovery fine, or VMDK is corrupt and you need to scan for VMK (Volume Master Keys).
Correct detection of encrypted disk will result in displaying a partition with “Bitlocker” file system at the disk list.

Force open disk as Bitlocker

Otherwise, please enable “Developer” mode by going to “View->Preferences”, press CTRL+E, check “Developer Mode” option and click “Ok” to save settings. Now right click on the disk with Bitlocker volume and select “Open as Bitlocker”. Btw. developers have promised to introduce this feature to user mode operations in the next build. See if they will keep this promise.

Scanning disk as Bitlocker

One way or another you Volume Master Keys are to be found and volume should be recognized as Bitlocker encrypted disk. Double click on it to open and enter the password user used to access this volume or recovery key.

Browse files and folders inside and check with built-in preview if they are recoverable. If data was decrypted successfully, you should see a correct preview of the files. I.e. Documents\multimedia\databases, etc.
