Well, first off, you can only 'return' something if it has a valid source address. chio status -S will likely tell you if that is the case. If it doesn't have a valid source address (this can happen if the drive doesn't support source element addresses or if the changer was powered on or reset after the element made it into its current location), you can't return it. chio move should always work, as long as the source and destination are valid.
