Can repair-bde.exe from Windows 7 (x64) unlock a Bitlocker-encrypted drive from Vista x32? RRS feed

  • Question

  • Hello,

    The Bitlock-encrypted installation of Vista on my laptop will not boot. I can get past Bitlocker allright by entering the password, but Vista then fails to boot with a Windows-related error message. My priority at this point is to first of all recover all data from that drive.

    I have removed the hard drive from the laptop and put it inside a hard drive enclosure. I am now attempting to use repair-bde.exe on another computer (Windows 7 x64) to copy out the (decrypted) contents of my laptop drive to a place on the Windows 7 machine. However, when I run:

    repair-bde.exe O: Z:\vista.img -rp ******  -lf myrepair.log

    this is all the output I get:

    BitLocker Drive Encryption: Repair Tool version 6.1.7601
    Copyright (C) Microsoft Corporation.

    Beginning scan for BitLocker metadata.

    Scanning boot sectors for pointer to metadata: 100%
    Finished scanning for BitLocker metadata.
    Beginning decryption.
    Decrypting:   1% Complete.

    After that nothing ever changes, even if I leave things running for a whole day. The log file ends up containing only this:

    ▒▒L O G   I N F O :   0 x 0 0 0 0 0 0 2 7
     V a l i d   m e t a d a t a   a t   o f f s e t   3 3 3 7 5 5 5 9 6 8   f o u n d   a t   s c a n   l e v e l   1 .
     L O G   I N F O :   0 x 0 0 0 0 0 0 2 8
     S u c c e s s f u l l y   c r e a t e d   r e p a i r   c o n t e x t .

    It looks as if repair-bde fails, but will not report it. I wonder, furthermore, if the problem lies in the fact that the drive was encrypted on a Vista x32 machine but that I am running repair-bde on a Windows 7 x64 box? An x32/x64 incompatibility would also explain why there is a whitespace next to every output character in the log file... Is my suspicion correct? Must I be running repair-bde necessarily on a Vista box, and an x32 one at that? Or can I maybe get away with using a repair-bde instance from a Vista x32 installation CD under Windows 7 (hoping that Windows 7 will be able to run an x32 executable in some intelligent compatibility mode)?

    Thanks in advance!
