um, if you've plugged in one device with a certain UUID and you've got a mount point and an /etc/fstab entry for it and then plug in another i suspect the 2nd device would not cause anything to happen. what you might want to do is unplug the working device and then plug in the one that doesn't work and use a partitioner to set up a new partition table and a new (and different UUID). see if that helps. :) good luck. songbird
