I had to dig into my remote queue on another system to find the
response from Thorsten Glaser <tygs_(_at_)_netcologne_(_dot_)_de>. Fortunately, I'm
a little better with qmail than I am with disk geometry.
Thanks, Thorsten, for the response.

He suggested, 'specifically you want "b <RET> 0 <RET> * <RET>".'
When I do this (in disklabel), I get:
total sectors: 139264
free sectors: 139264
This is only slightly better than when I told it to use the disk
geometry with "g d", rather disappointing for a 40GB disk.

He also suggested that I should read the man page. Unfortunately,
this really doesn't shed any light on the problem for me.
Can anyone help?
