I have a Mac running OS X Lion 2.8 Intel Core 320 GB hard drive built in, and 10 sd cards with photos on them have run out of space on the hard drive. Do have a 2 tr bit time machine that has been backing up great. So purchased second on to act as a external hard drive. for 200 gb and fast growing photo files and movie collection. can some one walk me thru setting this up both time capsules are showing up in finder. the one is still backing up and the new one only has a Data file in it but can't move anything into it.
