Thanks all for the responses this far. George -- this is the question I would 
be asking next, so I too am interested in knowing if we could continue to use 
LTO3 tapes once we have replaced all drives in the library to LTO4.

Subject: [Networker] Using LTO3 in LTO4 drives?

Is it a problem to recycle older LTO-3 media in LTO-4 drives and label 
these into the same tape pool? This is in an all LTO-4 drive tape library.

I've had no issues reading from LTO3 tapes in the LTO4 drives, and they 
are supposed to be backward write compatible (haven't tried that yet), 
but will NW span mixed tapes properly, assuming all drives are LTO4?
