You can use this image in VirtualBox as is, but depending on the guest OS it might not be visible immediately. Then you can create a file for VirtualBox that references this image: VBoxManage internalcommands createrawvmdk -filename 'usbdrv.vmdk' -rawdisk 'usbdrv.img' Here's how to use a flat disk image in VirtualBox:įirst you create an image with dd in the usual way: dd bs=512 count=60000 if=/dev/zero of=usbdrv.img To answer TJJ: But is it also possible to do this without copying the whole file? So, just to somehow create an additional vmdk-metafile, that references the raw dd-image.
