I was going to increase one of my VDI to 80 GB with the command:
VBoxManage modifyhd MY_DISK.vdi --resize 819200
Yes, a wrong additional zero was gone there. Of course, as an idiot I hadn't a backup.
So I really would like to decrease this size to the desired 80 GB. Unfortunatelly, just running resize again can't do it, since the
--resize only increases the size.
--compact too, but it only affects physical size. Is there anything can I do to change the logical size of my Virtual Box Disk Image?
