you could grab the serial number for sda through something like `sudo smartctl -a /dev/sda | grep Serial` or doing `ls -l /dev/disk/by-id | grep sda` and then, when you are changing disks, look for the serial number of the dead disk. this assumes that either you can take the box down to look at the serial numbers of each drive or you can see the serial numbers without disconnecting them. definitely something worth doing to verify which disk is which. mike /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
