[Beowulf] Drive screw fixed with LocTite

Perhaps the hole for that screw was defective (e.g., somebody tried to screw
in a screw one size too big) and rather than replace the case, he covered
his mistake with the loctite.

I'm still mistified by the hard drive soldered into the case of a brand-name
computer, the trend to preventing user maintenance makes me nuts, and
sometimes gets excessive, but in a hot-swappable array it would be patently
oxymoronic. I think just some coincidence of mistakes.
