BitLocker USB Drive showing as Incorrect Function

Question

it's a sad day when I need to post to the forum for help but I cant find a solution for this.
On a Windows 10 laptop I started Decrypting BitLocker ready to clone the disk. this failed at about 25%, I spent hours trying to get the SSD to finish unlocking. in the end I put in a new disk and started with a fresh copy of windows.
I still want to get the data of the old SSD so I have put it in a USB case. when I plug it into the machine it shows up as D drive but as "Incorrect Function" so there is no way to access the Bitlocker to Go command. if I try to access the drive via the Manage Bde command I get eh volume does not exist message, I do have the key printed out, i just need a way into the drive.

Hello Paul,

Thank you for your question and for reaching out with your question today.

I’m sorry to hear that you’re having this issue. Because you have the BitLocker recovery key printed out, you can try a few steps to access the data:

1. Open an elevated Command Prompt and use the following command:

   manage-bde -unlock D: -RecoveryPassword YOUR_RECOVERY_KEY
  
 In the above command replace  `YOUR_RECOVERY_KEY` with your actual recovery key.

2. You can also try opening the Control Panel, going to "System and Security," then "BitLocker Drive Encryption." Under the drive, you should see an option to "Unlock drive." Use your recovery key to unlock it.

3. Run PowerShell as Administrator and use the following command:

 Unlock-BitLocker -MountPoint "D:" -Password (Get-BitLockerVolume -MountPoint "D:").KeyProtector[1].RecoveryPassword
