Hi!

Welcome to Microsoft Q&A forum.

Let me tell you what's happening and what you can do. When you transferred your previous hard drive to a new machine, Windows registered a hardware change. BitLocker sees that as a likely theft attempt → locks the drive until you demonstrate ownership using the 48-digit recovery key.

The fact that you have the Recovery ID is useful, it does not unlock the drive automatically, it just helps identify which recovery key belongs to this drive.

Please follow these steps on how to check the key:

Even if you don’t remember the exact email:

Go to: https://account.microsoft.com/devices/recoverykey
Sign in with any Microsoft accounts you might have used (Hotmail, Outlook, Live, Xbox, Skype, even old work/school accounts).
Match the Recovery ID you see on screen with the one displayed when unlocking.

If you cannot find it there is no way to bypass BitLocker encryption. The whole point is to protect data even if the drive is stolen.

First I believe you misread the OP's problem."Transferring" the HDD was not mentioned. The OP said "replaced" and was using the original HDD as a secondary drive.

Though it is not specifically mentioned, I think the OP installed Windows to the SSD. That too would trigger the bitlocker issue. As for the data, it will still be accessible from the original HDD if the drive wasn't formatted and or erasing the original data.

To the OP, what steps or actions did you perform of those drives? More details needed. And did you backup your data to say another HDD or USB drive?

You might call MS to see if they can recover the account, then you can recover the bitlocker key.

As I mentioned, if you did not format the original drive, you can access the existing data. Purchase a USB external HDD/SSD enclosure ($10). Place your drive in it, plug it into another PC. Navigate the file system (folders) to your personal data.
