And .vmdk's are also used to describe and hold storage for virtual
drives in VirtualBox.
VirtualBox supports any .vmdk from a VMWare environment without OVF.
Just the .vmdk alone will work within virtualbox.

So the virtual hard disks that OP was seeing were in fact virtual
drives, *not* physical raw disks/partitions.

Start uncovering the many advantages of virtual appliances
and start using them to simplify application deployment and
accelerate your shift to cloud computing.
