createrawvmdk with partition switch: sharing violation

[Martin Huebner]

Good afternoon,

after a flawless installation of a W2K Professional SP4 Guest on a Vista SP1 Host (not all of my programs are cooperating well with Vista) I tried to enable the raw hard disk support of Virtual Box.

I have several NTFS-Partitions, the last one listed is intended to be accessible to the guest.

The listpartitions command gives me the partition no. 4:

VBoxManage internalcommands listpartitions -rawdisk \.\PhysicalDrive1

Output: VirtualBox Command Line Management Interface Version 1.5.6 (C) 2005-2008 innotek GmbH All rights reserved.

Number Type StartCHS EndCHS Size (MiB) Start (Sect) 1 0x27 0 /32 /33 130 /170/40 1024 2048 2 0x07 130 /171/1 1023/254/63 30728 2099223 5 0x07 1023/1 /2 1023/254/63 102437 65031184 6 0x07 1023/1 /1 1023/254/63 5122 274824018 4 0x07 1023/0 /1 1023/254/63 13311 285314400

O.K., so I entered:

VBoxManage internalcommands createrawvmdk -filename "C:\P4.vmdk" -rawdisk \.\PhysicalDrive1 - partitions 4

Output: ERROR: VMDK: could not create new partition data file 'C:\P4-pt.vmdk' Error code VERR_SHARING_VIOLATION at C:\vbox\branch\w32-1.5\src\VBox\Devices\Storage\VmdkHDDCore.cpp(2224) in function vmdkCreateImage Error while creating the raw disk VMDK: VERR_SHARING_VIOLATION

Even dismounting the partition by removing the drive letter in Vista's Disk Management leads to the same effect.

Omitting the -partition parameter works, no sharing violation, but then all my physical partitions are accessible to the guest.

Any suggestions would be appreciated. Thanks in advance.

Should be fixed in VBox 5.0, see the new -relative switch in #14268, all remaining issues regarding raw disk access on Windows should go there.
