Out of the different cdrom drives I've disassembled... dust and dirt,

a school with dozens and dozens of Goldstar branded cdrom drives that
would spontaneously and randomly eject their trays. It turned out the
plating on the switches was crap and when the switch wouldn't reliably
register that the tray was closed, the drive would eject the tray. Had
they either plated the contacts properly or had better switch debounce
logic the drives probably would have been fine. In the end, we replaced
them all and I kept a half dozen around to tinker with.
Well, unless your DNS server has crashed for some
perfectly valid
reason. Say, maybe, the janitor bumped into the server rack and
accidentally ejected a hot-swap drive and caused a kernel panic. I've
heard of that happening (to companies who subsequently either got rack
doors or stopped letting the janitors clean the server room).
I was assuming it was a non-trivial fault. I'm used to DNS servers not
failing I guess. ;)
My home DNS server crashed when my CD-ROM drive failed once...kept
running until I tried to update the zonefile.
HOW DOES A CD-ROM DRIVE SPONTANEOUSLY FAIL?!
