Too quick on the trigger.<br><br>Third, I believe drutil will only work if the disk is in a burner. diskutil should work on a non-burning drive. Find out the device name (System Profiler is the easiest way), and use, in a terminal:<br>
<br>diskutil unmount /dev/diskX (probably 1 or 2)<br>diskutil eject /dev/diskX<br><br><br>
