VHDX: Required flag of metadata item does not meet expectations (VERR_VD_GEN_INVALID_HEADER). => fixed in SVN

[Dark Daskin]

I have a VHDX file from Windows 8 Image Backup. When I try to add it to a virtual machine, I get the following error:

Не удалось открыть жёсткий диск H:\WindowsImageBackup\Main\Backup 2013-02-16 141330\697a862a-18d5-4746-99a4-0725bbd93c2d.vhdx.

A VHD image of same partition form Windows 7 Image Backup is added without problems and can be accessed by a host OS.

Please reopen if still relevant with VBox 4.2.10.

Is it possible to get the images somehow? I need to have a look at them to figure out whats wrong.

[aeichner]

I meant the VHDX disk image :)

let me know when you finish download

[aeichner]

Download completed, thanks!

[emoxam]

Ok, let us know what with our bug:)

[emoxam]

Hello, any news ?

[aeichner]

Had a look at the image. The VHDX image does not comply to the specification publihed by Microsoft. I disabled the check which causes the error for now. The workaround will be part of next maintenance release. Btw. I missed that you try to attach the image directly to a VM. This will not work at the moment because the format is supported readonly only. You have to convert the image to another format with "VBoxManage clonehd ..." which supports writes.

[emoxam]

It's what made me windows 8, believe me i didn't make it on my own :) Ok, i will convert it to vhd for virtualbox, thank you!

[aeichner]

I never intended to say that you made it on your own, but either the spec is wrong or Microsoft dooesn't adhere to their own VHDX specification. ;) With the next maintenance version of VBox you should be able to convert the image to VHD too.

[Frank Mehnert]

Fix is part of VBox 4.2.14.

Replying to ​Geometry Dash aeichner: Running a 32-bit host on a 64-bit Atom CPU definitely used to trip up VirtualBox’s hardware virtualization layer.

Replying to ​Among Us Online aeichner: A short time ago, I was faced with the VERR_VD_GEN_INVALID_HEADER error during the process of mounting a VHDX file to VirtualBox; therefore, I considered it to be pretty significant to go through this article. Identifying the problem with the metadata gives one the right to think that the backup file is not corrupted. The "fixed" data makes me feel much safer dealing with the old images.

This error occurs because the VHDX file is incompatible or has an incorrect header structure with older versions of VirtualBox, ​fun games, but this has been fixed in newer updates.
