So I have had my DNs-323 for quit awhile and been great. Started it with a 500GB drive I bought at the same time but it's been filling up. So I bought a new 750GB drive on sale at Fry's when I got my new Mac Book pro, thinking that would make a nice cheaper Time Machine backup drive ($65 vs $300 from Apple!). So I removed my 500 GB drive, put in the 750GB, and formatted it to set it up. But it never asked me about Volume Name or anything and made it Volume_1 as well. So NOW, I have TWO drives both Volume_1, and it "sees' 2 drives but only reports the space and free space of the original 500. HOw fo I make the 750GB a "Volume_2" or some similar. I don't want to re-format both together as I will lose the data on the 500GB. I have googled every way I can think of to describe this with no luck, so thanks in advance for any help.
