Logical size: 40960 MBytes Current size on disk: 18464 MBytes Type: normal (base) Storage format: VDI Format variant: dynamic default ... and also reports the same logical size for the snapshot files. The problem is that gparted reports that the drive is still 20G (not the partition; the whole drive). Windows disk management also sees the drive as 20G. It looks like while VirtualBox can see the new logical size, it's not reporting it to the guest correctly." defect reopened virtual disk VirtualBox 4.0.8 modifyhd resize other Linux
