BitLocker-protected drive insert into a different computer - Windows 7 RRS feed

  • Question

  • Hello everyone,

    I have a question with regards to mounting an OS drive from another PC in Windows 7 Laptop. (via a docking station Bay)

    (this drive has two partitions C: OS, D: Data - both with Bitlocker enabled)

    I have tried starting Windows7 from the laptop first (laptop drive has Bitlocker enabled)

    After that i have an Win7 OS drive from another PC, loaded in the docking station (this drive is also a Bitlocker protected OS drive) docked with the laptop. Normally, for non Bitlocker drive, the new drive's paritiions will be displayed without problem. However, the result i have is i can not see the drive from the other PC at all inside Windows 7 started by the laptop OS drive. It appears that this disk is not even recognized at all.

    I have checked the website and found the following below with no luck at all...I have the correct recovery key ready, not using DRA though.

    Would anyone be able to help me with more details on how to mount the drive in Windows7 in this case? Or can this be done at all?


    Many thanks

    Can I access my BitLocker-protected drive if I insert the hard disk into a different computer?

    Yes, if the drive is a data drive, you can unlock it from the BitLocker Drive Encryption Control Panel item just as you would any other data drive by using a password or smart card. If the data drive was configured for automatic unlock only, you will have to unlock it by using the recovery key. If it is an operating system drive mounted on another computer running Windows 7, the encrypted hard disk can be unlocked by a data recovery agent if one was configured or it can be unlocked by using the recovery key.

    Note Mounting the hard disk on another computer running Windows 7 is a quick and straightforward way to recover information from a damaged computer that has a BitLocker-protected drive on the hard disk.

  • Ray,

    Have you used the following steps to create and use a data recovery agent ?

  • cschaar,

    Thank you for the link.

    I have tried that already. But the drive does not appear when attached to the PC. Hence, no command can be executed.

  • The quote in the first post provided the answer. It is an OS drive, not a data only drive. Unless it's in the original hardware configuration as a boot drive, BitLocker will not unlock due to the hardware change.

  • So, if I understand you well, it would help to remove the hd from the docking station and reinstall it in the original workstation (laptop). But, what if the OS of the original working changed in the mean time (updated or re-installed)?

    The latter is the case with my laptop, it crashed during one-of-so-many windows 10 updates. Using the unlock key on the docking station indeed doesn't work. So much for bitlocker, another word for ransomware so it seems...
