No...I have one of these at home hooked up to a u34f SCSI card on a system
running 2.0.31. I can mount all 7 CDs and go back and forth between
looking at each of them. It automatically swaps the CDs around and loads
the one I'm currently using. I've heard you can do nasty things to the
system by intentionally forcing it to swap CDs around much faster than
it's capable of, but haven't ever tried breaking it that way.
