How can I do this in 4.0.0 as some of the forums I have seen refer to earlier versions and the instructions don't seem to work on my version.
My PC is Windows 7 Home Premium.
Any help appreciated - thanks.
A hard disk is a hard disk - a piece of metal and electronics in the real world. A disk image is an image of a hard disk (usually), i.e. a sector for sector copy of the disk contents. But, since VirtualBox typically works with virtual hard disks - which are actually disk images - the terms "(virtual) hard disk" and "disk image" are usually interchangeable in the VBox world.hank wrote:I think a "hard disk" and a "disk image" mean the same thing, and a "VDI" is different
Look again - what I think you've seen is that you can attach multiple hard disks to a VM (a Virtual Machine), which is something else entirely: a VM is a simulation of a complete PC, a VDI is just a disk image.hank wrote:I see repeated references in the manual to attaching multiple hard disks to a single VDI.
Yes, it's an instruction for creating an entirely new (blank, unformatted) VDI. AFAIK the GUI provides no means for duplicating an existing disk image: that's one of my original reasons for writing CloneVDI.hank wrote:I was puzzled because I had read earlier in the 4.0.2 manual p. 76 Ch. 05:
-- "Starting with version 4.0, to create new disk images, please use the “Storage” page in a virtual machine’s settings dialog"
Is that instruction only for creating an entirely new disk image -- but not to be used to create a duplicate hard disk image file?
