They get stacked, piled, fall behind the systems, and a DLT cartridge works really well as a coaster for a coffee mug. (We wouldn’t want to get any coffee rings on the new server, right?)

Have you ever really needed a volume and couldn’t find it? I’ve been there. It’s a horrible feeling to know that you’ve got the file on a volume, but can’t find the darn volume!
