I'm trying to obtain the 48-digit BitLocker recovery key from a failed drive. Here's what happened:
Windows 10 Professional was installed on a Samsung 980 Pro 2TB drive. The login was a local user account with no password. No Microsoft account was used.
Bitlocker was enabled. The computer after power on goes to the Windows desktop with no user input required (and with the drive unlocked).
Samsung 980 Pro 2TB drive fails due to bug in firmware 3B2QGXA7. The drive is in permanent read-only mode, with most of the data still intact.
Due to the read-only mode, Windows cannot boot normally. Windows also cannot enter recovery mode.
I used Clonezilla to make a disk image of the failed drive for future recovery.
I used Clonezilla to copy the entire Samsung drive onto a known good drive. Windows on Good drive still cannot boot normally. Windows on Good drive can now enter recovery mode with an admin command prompt.
Now I can try to obtain the 48-digit BitLocker recovery key via the command prompt.

Here's where I'm stuck. In normal situations, manage-bde -protectors C: -get
would return the 48-digit recovery key. But in my case it says No key protectors found
