Great. That answers my question exactly.

Filesystem    Size   Used  Avail Capacity  Mounted on
/dev/da0s1a    97M    62M    27M    70%    /
/dev/da0s1e   7.7G   6.2G   900M    88%    /usr
/dev/ad0s1e    72G    66G   772M    99%    /home
procfs        4.0K   4.0K     0B   100%    /proc

So I'm booting off of a SCSI disk da0.

I want to replace ad0s1e with the new 300GB monster.

But not in my case since this disk is just storage I think, right. Actually,
when I run the disklabel do I need to use -B at all. I don't need a bootstrap
since its not a boot disk, right?

Thanks,
Alex
