For one thing, it probably looks a bit shady carrying that many hard drives, y'know "What have they got on them, are they really hard drives at all, can we please hold on to these sir?" And I worry that stray magnetism from the metal detector wand could wipe them out all at once. Would it be better to put (some of) them in check-in luggage instead or is that stupider? I've even heard of the magnetism of the motor that drives the conveyor belt through the x-ray machine being blamed for data loss.

Tell me your stories. Preferably the boring uneventful kind where everyone's data lives happily ever after.
