Heh, I see where the confusion lies. The cylinder/head/sector values for
scsi drives are ficticious. They are approximations calculated by the
kernel. The "8386733 sectors" is what is reported by the drive itself.

I need to look into why this is causing problems for the disklabel code.

In the meantime, your workaround should at least be able to get you up and
running.
