access denied on raw disk

[harald123]

Hi,

I had setup a raw disk to boot from usb drives which was working fine. About a month ago I upgraded Virtualbox version and now the vm is not starting anymore and shows 'not acessible' in the Gui at the raw disk file.
I start VB with admin rights and also gave full control on the raw disk file to everyone. Diisk management says the disk is healthy.
Reboot also does not solve it.
Is it possible that the update broke this setup in a way?
I read other topics with this error, but could not find a solution except the one with diskpart.

Error when trying to boot the vm:

0:00:12.740763 Power up failed (vrc=VINF_SUCCESS, rc=E_FAIL (0X80004005))

Error when trying to setup the raw disk again with vboxmanage:

C:\Program Files\Oracle\VirtualBox>VBoxManage internalcommands createrawvmdk -filename c:\usb.vmdk -rawdisk \\.\PhysicalDrive1

The 'createrawvdk' subcommand is deprecated. The equivalent functionality is
available using the 'VBoxManage createmedium' command and should be used
instead. See 'VBoxManage help createmedium' for details.

About a month ago I upgraded Virtualbox

The new Virtualbox version 7.0 has some changes for Raw Disk Access. I haven't played with it lately, so I'm not certain what to change in your setup. See https://www.virtualbox.org/manual/ch09.html#rawdisk and "VBoxManage createmedium".

ok, I tried with createmedium as well and it looks the same:

C:\Program Files\Oracle\VirtualBox>VBoxManage createmedium disk --filename c:\usb.vmdk --format=VMDK --variant RawDisk --property RawDrive=\\.\PhysicalDrive1
0%...VBOX_E_FILE_ERROR
VBoxManage.exe: error: Failed to create medium

VERR_ACCESS_DENIED

Please check that you're running this command in a Run-as-Administrator command prompt. Also:

--filename c:\usb.vmdk

Put the file in a subfolder, not the C drive root. Windows has special permissions for drive roots, especially C:\.

Also, the disk being accessed has to be off-line in the Windows host Disk Management.

ok, I ran cmd as admin and used a test folder c:\test\usb.vmdk with the same error.

I tried to make the disk offline and it says it cannot do it for removable media:

Disk 1 Online 1928 MB 0 B

DISKPART> select disk 1

Disk 1 is now the selected disk.

DISKPART> offline disk

Virtual Disk Service error:
The operation is not supported on removable media.

LE:
maybe it is a bug that can be reported to dev
