I have a Linux guest with VDI hard drive.
I want to attach the physical (on host) hard drive to this guest.

So I created the ada3.vmdk pointing to /dev/ada3:
VBoxManage internalcommands createrawvmdk -filename ada3.vmdk -rawdisk 
/dev/ada3
Then I ran this command to attach ada3.vmdk to the machine Mint-mate-32:
VBoxManage storageattach "Mint-mate-32" --storagectl "SATA" --port 1 
--device 0 --type hdd --medium "/home/yuri/VirtualBox 
VMs/Mint-mate-32/ada3.vmdk"

This added another HardDrive in Mint-mate-32.vbox:
<HardDisk uuid="{408da1c6-8939-42d3-a03b-da6d3c4d36ad}" 
location="ada3.vmdk" format="VMDK" type="Normal"/>
And also this hard drive's description under <StorageController 
name="SATA" type="AHCI" PortCount="2" useHostIOCache="false" 
Bootable="true" IDE0MasterEmulationPort="0" IDE0SlaveEmulationPort="1" 
IDE1MasterEmulationPort="2" IDE1SlaveEmulationPort="3">:
      <AttachedDevice type="HardDisk" port="1" device="0">
         <Image uuid="{408da1c6-8939-42d3-a03b-da6d3c4d36ad}"/>
       </AttachedDevice>

However, this machine fails to start now: VERR_ACCESS_DENIED on ada3.vmdk
No further explanation, except NS_ERROR_FAILURE (0x80004005)
Log provides no further insight also.

Hard drive is recognized by the host system as:
ada3 at ahcich7 bus 0 scbus7 target 0 lun 0
ada3: <WDC WD1600BEVT-22ZCT0 11.01A11> ATA-8 SATA 2.x device
ada3: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes)
ada3: Command Queueing enabled
ada3: 152627MB (312581808 512 byte sectors: 16H 63S/T 16383C)

How can I get information what the error actually is?
Is such operation reasonable? Is it supposed to work?
