I run a weekly cron job that calculates md5sums for all the files on the media drive. Then it compares it to the previous weeks and emails the diff. If anything goes wrong I restore the file from one of my backups and check the MD5 again. I did have one drive that was slowly losing data. Turned out to be a dodgy sata port/cable but I've not lost a file yet.

Maybe that's because you aren't as smart as the creator. Not saying that's the case but if I can't figure out why someone is doing something it's usually because I don't know as much as they do. I don't just assume it's because they're crazy.

Seriously guys, he's a philosopher. I'm surprised no-one here has pointed out that it's the Helium that is keeping the moon floating way up there. Take the Helium away and it will sink back down to earth and we do not want that to happen. You think global warming is bad, just imagine how bad it would be with the Moon orbiting at 10000m. I guess we could try to time it so it touches down in the Sahara but if it overshoots it's goodbye Panama.

The speed of anything depends on the flow of everything.
