RawDisk is creating an invalid .vmdk file => fixed in svn/7.0.x x>2

Previously discussed in

VirtualBox 6.1.x creates a working .vmdk for this disk.

Is it possible that the disk sector size of 512Bytes is causing problems?

In the forum thread, the VMDK file had the following obviously wrong geometry settings (missing in the Description above):


Since the physical disk is larger than 8 GB, ddb.geometry.cylinders should be "16383". Additionally, the last extent specification is probably much too large (~18,000 TB ;)).

Similar issues have been reported when creating a raw disk vmdk with 'VBoxManage createmedium' on Linux.

Thanks for the report. The implementation of the functionality provided by 'VBoxManage createmedium disk --Variant Rawdisk ...' in VirtualBox 7.0.0 is incomplete as a small but key detail was overlooked. The root cause of this issue is known and a fix is in progress.

Testing with VirtualBox 7.0.3 is successful for both full disk and partitioned VMDKs.

VirtualBox 7.0.4 was just released and available for download at This issue should be fixed in this version.

I'm using:

$ VBoxManage --version

And problem was still there... (Trying to access /dev/sdb , a USB thumbdrive in my case) until I started:

qemu-system-x86_64 -m 2048 /dev/sdb

and re-ran the VBox command while qemu was running, and then it worked! WTF!?!
