Ever heard the old, old m'frame (I think) story, of the guy who needed to
do a backup, and the tape failed, and they had to go to an older one. The
next few days, he was trying to find out why, and discovered all of the
tapes on the bottom row of the tape (reel) rack were bad. Stayed late one
day, working on it... and watched as the cleaner came in, and ran the
floor cleaner right up to the rack....
