Bitlocker Problem in second partition

Question

Hi, i want to ask for help..
I have a notebook with SSD M.2 NVME 2 TB. Then i split the SSD into 2 partition (drive C and drive D).

One day, my notebook broke and totally dead because of motherboard problem.

When i try to open the SSD into another laptop, the system asks for 48 digit recovery key.

After reading some articles, i check my microsoft account and found 48 digit of recovery key of drive C:

After i inputted the 48 recovery digits, i can access to Drive C:

but unfortunately my Drive D: was still in lock condition and also asks 48 digit recovery key.

i tried to input the same 48 digit recovery key for Drive C: but the D Drive could be opened.

I tried to use cmd prompt "manage-bde -protectors d:" but there is no password.

Is there anything that i can do for opening the D Drive?

thank you very much

Best Regards

Budiman

Answer 1

I am very familiar with all sorts of Bitlocker issues and setups.
Yes, it's possible to access d: and I am pretty sure I have saved the steps for that somewhere in my notebook.
I will try to find it.

The d: drive was set to auto-unlock and that means, its keys are saved on c:, which you have access to - thus, it's recoverable.
