ATI 2021 "Unable to back up locked volume" but Bitlocker is confirmedoff!

Thread needs solution

I have used ATI bootable many times to make backups of my laptops.  Today I went to backup my new Windows 11 laptop.  Bitlocker is confirmed as OFF in Windows.  Yet, when I select the volume Acronis thinks that bitlocker is enabled.  It continually says "Unable to back up a locked volume encrypted with BitLocker."   The SSD is a Samsung Evo 970 NVME (not that I think that should matter!).  Machine is a Lenovo T14.  We have NEVER EVER had Bitlocker on either!

I tried an old USB Acronis 2020 bootable I had and I got the same thing.  So... for some reason Acronis thinks this drive is encrypted when it's not.  Any ideas on that?

Turns out that even though CONTROL PANEL and THIS PC showed BitLocker off, COMPMGMT.MSC showed it on. WOW!  WE disabled via PowerShell to fix:

 

  1. Open Windows Powershell in Administrator mode and execute the following commands 
    • PS C:\>$BLV = Get-BitLockerVolume
    • PS C:\>Disable-BitLocker -MountPoint $BLV
  2. Verify the decryption process by using below method
    • Execute command: PS C:\> Get-BitlocerVolume
    • Check decryption progress in "Volume Status"  & "Encryption Percentage". Also these values must be "FullyDecrypted" & 100%  to confirm the decryption completion.

Glad you worked out what the issue was; this is the second recent report of incorrect information about BitLocker status.
