If anything it seems = to strengthen it because standalone DDR wouldn't have access to whatever = is doing the tape handling. I don't think you meant we wouldn't need standalone DDR because that will always be needed as a last resort for = when CMS is not available, and therefore it has to be able to read what = CMS DDR wrote. This requires the media handling function to be part of = standalone DDR, which seems contrary to your comment. Please clarify in = case I misunderstood you. Brian Nielsen
