More than that.

Yes, it's because the wd driver trusts the geometry reported by the
drive, and telling the drive to use the geometry that it reported
doesn't work right at least if the WD1007 is jumpered to use a fixed
geometry (I think setting the geometry doesn't work, but no error
is reported).
