I have a VHD that's running out of disk space. The current size is 16GB which is what Virtual PC defaults to, unfortunately I can't see any way to specify the size, at least in the version that I'm using. I used VirtualPC for the build but it's now living on Windows Virtual Server.

I've created a dynamically expanding VHD (with a size that I've specified) easily but I need to clone the contents of the first disk into the second. We have an old version of ghost but I can't get the boot floppies to even boot into ghost. There must be a better way of doing it.

I've found http://ping.windowsdream.com but I don't know if this can do what I want. I could also use the following DD command:
dd if=/dev/hda of=/dev/hdb
but I've read that Linux can handle NTFS but doesn't know about ACLs so it wouldn't boot? Does anyone have any suggestions?
