Yes,fakeRAID metadata is stored somewhere close to the end of the harddrive, and is used by dmraid to figure out what your raid setup is. On a real machine, it is the BIOS job to write them, dmraid-empty-disk has the fake signature and this is good for testing. > Makes me wonder if we could not have a tool > to generate such images from scratch... I'm working on this, but it is not very simple for me. Approximately "dmraid -rD" generates three files, from this we can extrapolate metadata, and with a hex editor we can add the fake signature to the qemu/virtualbox drive Giuseppe.
