Yeah, that's probably not going to be an option *if* I go through with it... that's too much downtime, to be honest. I can pick up a couple extra 2GB drives or even pull some 500Gs that aren't in use to copy the data... that way my downtime is only about the time to shutdown, remove drives and install new ones... It houses about 3,000,000 photos right now and it's my busy time of year. I do, though, appreciate the insight and if push comes to shove and this occurs over the summer I will probably go that route. Thank you.
