I think you have been fooled by the horrible option change between Sdelete 1.5 and 1.6. the -c and -z options are inverted. When executing a 'clean' of the disk, this will efectively fill up your dynamic disk to it's maximum size. Use the <em>Zero Free Space</em> option, whatever it is called in your SDelete version!

"Expandable" means that VirtualBox will allocate physical HDD space on your Host only when Guest requests to use that space. Since sdelete.exe writes zeroes to free disk space, it will actually grow VDI to its maximal allowed size. Martin Skip sdelete.exe step in case your VDI image is “expandable”.
