I would like to make a VirtualBox .vdi image out of my hard drive.
I've found howto's online that describe doing this by first usind DD to create a .raw image, then using VBoxManage to convert the .raw to a .vdi. SO if my HD is 1 TB, this process (temporarily) requires 2TB of space, to store both the .raw and .vdi.
I only have a bit more than 1TB of free space. Is there a way to create a .vdi image of a hard drive, without first having to create a .raw image?
