Oh, that's a simple one: lack of time. I too have some very old data in an archive that's on some old hard drive somewhere in a storage. Assuming the HD still works, I could go in there, destroy the data, and trash it. But I'm fairly certain I will never find a moment to do so. Managing what data you keep is just too time consuming. Hoarding it all is simpler.
