Synopsis: disklabel fails to write labal on scsi disk

State-Changed-Why: 
I'm pretty sure this PR can be closed, though I will add another note:
sometimes there will be data on the disk that causes disklabel to barf,
even when you are trying to install a new label.  When this happens to
me I clear out the first 64K or so worth of the partition with dd and
then install a complete new label and boot program.  If you do this,
however, remember that using dd to clear the label will also clear
the boot blocks so always install new boot blocks :-) 

e.g.  dd if=/dev/zero of=THEPARTITION bs=64k count=1
(this will 'destroy' the disk, after which you can install a new
label & new boot blocks with disklabel)
