compact VM

so to wrap it up

inside of your virtual machine

1) pick the defragment tool of your choice and configure it to pack data as close together as possible - leaving large areas of free space

(I used http://www.oo-software.com/free/en O&O Defrag Free Edition - a very potent free defrag utility )

2) zero the free space with http://technet.microsoft.com/en-us/sysinternals/bb897443 sdelete

sdelete -c C:\ (on C:\)

or whatever other drive



outside of the virtual machine - on your host

3) VBoxManage modifyhd Disk.vdi --compact


disk worked like a charm and gained me 9 GiB worth of additional harddrive space on my /home partition - and that was only one of those harddisks

Thanks !
