While I'm sure you're being sarcastic, I wasn't. Some don't care, some have no clue. I'm frequently asked to resurrect someone's PC, but they've buggered the install discs up beyond any use. Some look like they've been used as the skids on a toboggan, and gone gone skating down a sand dune on them. Other's have finger prints all over them. Not just a mark around the edge where someone's had a bit of a trouble picking up a disc, they've smeared their fingers all over them with no care. And I've seen some damage to discs that I just can't figure out how they've done it. In all seriousness, if you don't look after important media, well you deserve losing it. -- (Currently running FC4, occasionally trying FC5.)
