I disagree on the alignment requirement. It's needed only for pack
interchangability. It's 2005, not 1975, and that probably no
longer matters. Use a tape, or ftp :-)

What you actually want to do is align it to work with the OTHER packs
that came with the system!
I learned this the hard way a LONG time (20+ years) ago when I discovered
that none of the packs we had worked any more after I did a head alignment.
