Well, when we use blank disks, there is no problem, because windows is not
installed on it, right ? And if windows then fail, it is windows fault.
As for machines where disk has been moved, i don't get it. the partition table
is on disk, so using it is always ok, even if the disk was moved.

Well, i certainly have no problem at all with parted, but then i use a sane
partition table format (amiga one), and thus have not such problems. And i
indeed read the geometry from an existing one on the disk when reading the
partition table, and let parted create anything it thinks right when creating
a new partition table.

Well, you can simply open the device and overwrite bios_geometry, not ?
