[http403]

Version

Windows: 10 22H2
clonezilla-util: 2.0.4

Problem

Neither mount or mount-as-image-files can mount a BitLocker partition.

Step to reproduce

2. Enable BitLocker on drive
3. Clone with Clonezilla
4. Back to Windows
5. Attempt to mount it

Expected bahavior

Mount the disk for Windows or other decryption tool to decrypt

Actual bachvior

System.Exception: Unknown partclone image version: (undisplable text after b64e: Aw==)

Workaround

None

Command Used:

clonezilla-util mount -i .\laptop-backup -p nvme0n1p3 -m Z:\ --temp-folder E:\temp\
clonezilla-util mount-as-image-files -i .\laptop-backup -p nvme0n1p3 -m Z:\ --temp-folder E:\temp\

Traceback (Both commands have identical output)

Thanks Hartman,

I would really like to support Bitlockered images. But I need a library which can open them.

Cheers,
Fidel

Can just mount it encrypted and let Windows to handle the decryption process? Or the process of mounting a BitLocker image is significanly different than a normal image? I don't quite undersrand what you mean by "open".

[fiddyschmitt]

That's a really interesting idea.

Currently the program uses the Dokan library to create a virtual drive to mount. I have to give Dokan a list of files to show on the virtual drive - I can't just give it a raw img for it to serve to Windows. So I need a way to open BitLocker first, get a list of files, and pass them to Dokan.

But perhaps there's another way. Maybe we can convert the raw img to a VHD. Windows 10 can mount VHD files, and with luck, it should prompt for a BitLocker password to proceed.
