Encryption on a Virtual Endpoint Client (i.e. VMWare, Oracle Virtual Box or Microsoft Virtual PC) does not start. Console reports following error: 

D/MM/YYYY HH:MM:SS xM NT AUTHORITY\SYSTEM Error 2075 Querying disk properties or Opal disk initialization has failed. Internal code: 0x00000066.

If the drive has been initially setup using SCSI mode, the disk properties of the virtual machine may not be correctly evaluated by the Sophos Disk Encryption Client. For security reasons, the Client does not start to encrypt the drive.

What To Do

Change the hard disk controller mode for the virtual machine from SCSI to IDE. Changing the hard disk controller mode may require a fresh installation of the Operating System.
