I going to convert an existing centos 5 workstation to a VirtualBox VM I plan on doing a: dd if=/dev/sdb1 of=sdc1.img bs=1024 and then do a "VBoxManage convertfromraw" to create the VDI image. My question is: the Centos workstation lives on a 250gb drive, but only uses about 85gb. Is there an easy way to end up with a .VDI that is around a 100gb or so? :) Dave
