И особенно стоит обратить внимание на описание команды
--compact , a именно:
авторWith the --compact option, can be used to compact disk images,
i.e. remove blocks that only contains zeroes . This will shrink a dynamically allocated image again; it will reduce the physical size of the image without affecting the logical size of the virtual disk. Compaction works both for base images and for diff images created as part of a snapshot
Посему есть мнение, что дефрагментация образа и запуск утилиты очищающей (заполняющей 0x00) свободное пространство диска перед сжатием таки должны помочь автору темы.

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

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 [/quote]
