I wish I knew, Moonbear <img src="/ubbthreads/images/graemlins/puppyeyes.gif" alt="" /> (I checked all hiding places, but the alarms were on - we don't know) - the trouble is: we're not informed exactly about what was on that drive (though my colleague and I are system admins). Passing on security info is done in a very restrictive way.
We already lost a TFT monitor 3 months ago in the youth library and have to lock up rooms now, all TFT are secured with steel cables now (yuck) - yesterday we locked up all PC in safety cases, probably leading to our next prob: where are the damn keys! Yeah, we're good at losing them <img src="/ubbthreads/images/graemlins/shame.gif" alt="" /> And this was the reason, why the other system admin decided against locking up the PC - and I didn't know, the cases had been delivered already.
It's not easy to patrol, accomplish information duty, keep youngsters at a moderate noise lvl and check all the time. Since we've got those PC, we only have trouble. <img src="/ubbthreads/images/graemlins/cry.gif" alt="" /> Kids try to hack them constantly - but imagine this:
you're a lawful member, want to research in peace and quiet and have a dragon librarian breathing down your neck all the time, eyeing you suspiciously and asking all the time: what the heck are you doing? This distrust would aggravate me terribly. And some PC are in distant corners, so members don't have to walk the long way, overcome dangerous stairs, avoid spiteful shelves to research.
