write permission denied on rawdisk after drive encription

Hi all,

  on a windows10, after a drive encryption my virtualbox (Oracle) which was accessing to whole rawdisk get an error of write permission denied as the next one:

Apertura di una sessione per la Macchina Virtuale non riuscita.

Failed to open image 'C:\Users\Users\VirtualBox VMs\guix\linux.vmdk' for writing due to wrong permissions (VERR_VD_IMAGE_READ_ONLY).

PIIX3 cannot attach drive to the Primary Slave (VERR_VD_IMAGE_READ_ONLY).

 
 
 

 

the linux.vmdk isn't a conventional vmdk but contains access to raw disk:

# Disk DescriptorFile
version=1
CID=677b1f25
parentCID=ffffffff
createType="fullDevice"

# Extent description
RW 976773168 FLAT "\\.\PhysicalDrive0" 0

# The disk Data Base
#DDB

ddb.virtualHWVersion = "4"
ddb.adapterType="ide"
ddb.geometry.cylinders="16383"
ddb.geometry.heads="16"
ddb.geometry.sectors="63"
ddb.uuid.image="02a08bbf-6b01-452d-8cef-d7f80ac2d6a7"

ddb.geometry.biosCylinders="1024"

ddb.geometry.biosSectors="63"

 

 trying to recreace vmdk:

VBoxManage.exe internalcommands createrawvmdk -filename "C:\Users\BORMAU\VirtualBox VMs\guix\linux.vmdk" -rawdisk \\.\PhysicalDrive0
VBoxManage.exe: error: Cannot open the raw disk '\\.\PhysicalDrive0': VERR_SHARING_VIOLATION
VBoxManage.exe: error: The raw disk vmdk file was not created
