Maybe something as simple as building your kernel with
options         SCSI_DELAY=10001
or even larger.  Slow busses and some older hardware
do not like small values here.

Second, sysinstall is for installing the system, and is fairly
horrible for day&day ministering.  Better by far to learn the
command line utilities.

man fdisk
man bsdlabel
man newfs
and if you are going to be sharing it between machines
you might look into glabel.
